9x + 8 y = -6
-9x - 9y - 9
Elimination
Answer:
x = 2, y = -3
Step-by-step explanation:
Add them together and get
9x + 8y - 9x - 9y = -6 + 9
-y = 3
so y = -3.
Sub it into the first equation and get
9x + 8(-3) = -6
9x - 24 = -6
9x = -6 + 24 = 18
x = 18/9 = 2

Answer:
(b) 16 ft²
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h . . . . . where b1, b2 are the base lengths, h is the height
Using the values shown on the diagram, we find the area to be ...
A = 1/2(3 ft + 5 ft)(4 ft) = (1/2)(8 ft)(4 ft) = 16 ft²
The area of the trapezoid is 16 ft².

What is the constant of proportionality in this proportional relationship? PLS I WILL MAKE U BRAINLELIST
Answer:
The constant of proportionality is [tex]k=\frac{7}{9}[/tex]
Step-by-step explanation:
Recall that the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality.
Here, [tex]k=\frac{7}{9}[/tex] since [tex]2(\frac{7}{9})=\frac{14}{9}=1\frac{5}{9}[/tex], [tex]3(\frac{7}{9})=\frac{21}{9}=2\frac{3}{9}[/tex], and so on.
4. Lucy is k years old. She has a sister who is three years younger than she is and
another sister who is five years less than twice Lucy's age. Write an expression, in
simplified form, for the sum of the three girls' ages.
Answer:
4k - 8
Step-by-step explanation:
Lucy is k years old so we know k is an important part of this problem.
Sister 1 is 3 years younger, so she is k - 3 years old.
Sister 2 is 5 years less than twice Lucy's age therefore, she is 2k (twice Lucy's age) - 5 years old.
Now we have: k + (k - 3) + (2k - 5)
We can simplify like terms with the k's and get 4k. then we add (-3) and (-5) to get 4k - 8.
Hope this helps!

For every $3.00 donated to a certain charity by Club A, $1.25 was donated by Club B. If the combined total amount donated to the charity by both clubs was $25,500.00, how much did Club A donate?
Answer:
D, $18,000.00
Step-by-step explanation:
Club A
$3 x is donated where x is the number of donations
Club B
$1.25x is donated where x is the number of donations
The total of donations is 25500.00
Add the donations times the dollar amount for Club A and Club B and you get the total amount donated
$3x +$1.25x = 25500.00
Combine like terms
4.25x = 25500.00
Divide by 4.25 on each side
4.25/4.25x = 25500.00/4.25
x =6000
There were 6000 donations
We want to find Club A donation amount
$3 x is the amount donated
3*6000 = 18000

Your cellphone company charges a $18 monthly fee, plus $0.11 per minute of talk time. One month your cell phone bill was $70.80. How many minutes did you spend talking on the phone that month?
Answer:
480 minutes would be the answer
Step-by-step explanation:
Answer:
480 minutes
Step-by-step explanation:
We can write this relationship as [tex]y=0.11x+18[/tex] and then solve for x when y=70.80:
[tex]y=0.11x+18\\\\70.80=0.11x+18\\\\52.80=0.11x\\\\480=x[/tex]
Therefore, you spent 480 minutes talking.

The first polygon is a quadrilateral.
The second polygon is a pentagon.
Polygons:Polygons are flat or plane, two-dimensional closed shape with straight sides.
Polygons are classified base on the number of side they possess. For example polygon with 4 sides are called quadrilaterals, the ones with 8 sides are referred to as octagons.
Therefore, the polygons above have 4 sides and 5 sides respectively.
The polygon with 4 sides is know as a quadrilateral.

what is 6 20/97 as a improper fraction?
Answer:
120/97
Step-by-step explanation:
When you're turning a mixed fraction into an improper fraction, you keep the denominator (bottem number) the same, but you times the numerator (top number) by the whole number (non-fraction number/left number)
6 * 20 = 120
Therefore it should be 120/97

jenelle is planting a circular vegetable garden with a fence around the border. If she can use up to 50 feet of fence, what is the largest whole number radius she can use for the garden?
The Length of the fence in the example doubles as the perimeter of the circular garden. Hence the largest whole number of the radius is 8 feet
Mensuration of Plain Shapes (Circle)Given Data
Length of Fence = 50 feet
Largest Whole number Radius = ??
In this exercise, the Length of the fence is the same as the perimeter of the circular vegetable garden.
We know that the expression for the perimeter of a circle is given as
Perimeter of Circle = 2πr
From here we can solve for the Radius r
50 = 2*3.142*r
50 = 6.284r
divide both sides by 6.284
r = 50/6.284
r = 7.956 feet
r = 8 feet

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.
For example:
13 has only two factors, itself and 1. So, it is a prime number.
4 has three factors, itself, 1, and 2. So, it is not a prime number.

An artist has been hired to paint a mural of a sailboat on the side of a building. The original sailboat is 32 feet in length and has a mast height of 40 feet. The
artist will create the mural using a scale factor of 4:3 to relate the original dimensions to mural dimensions.
How tall will the mast of the sailboat be in the mural?
_____ ft?
Answer:
30 feet
Step-by-step explanation:
A ratio of 4:3 means that if one part can be represented by x, the original height is equal to 4 * x and the mural height is equal to 3 * x. This is because the ratio of original : mural is 4 : 3, so if one part = x, we have 4 * x : 3 * x. Therefore,
original mast height = 40 feet
4 * x = original mast height = 40 feet
divide both sides by 4 to get x
x = 10 feet
3 * x = mural mast height = 3 * 10 feet = 30 feet
[tex] \frac{5}{3} + \frac{4}{6} = [/tex]
.................
Answer:
[tex]\frac{7}{3} =2\frac{1}{3}[/tex]
Step-by-step explanation:
For the problem:
[tex]\frac{5}{3} +\frac{4}{6} = ?[/tex]
The Least Common Multiple (LCM) of 3 and 6 is 6. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:
[tex]\frac{5}{3} +\frac{4}{6} =\frac{5*2}{3*2} +\frac{4}{6} =\frac{10}{6} +\frac{4}{6}[/tex]
Now that the fractions have like denominators, add the numerators:
[tex]\frac{10}{6} +\frac{4}{6} =\frac{10+4}{6} =\frac{14}{6}[/tex]
The Greatest Common Factor (GCF) of 14 and 6 is 2. The result can be simplified by dividing both the numerator and denominator by 2.
[tex]\frac{14}{6} =\frac{14/2}{6/2} =\frac{7}{3}[/tex]
7 ÷ 3 = 2R1, therefore:
[tex]\frac{7}{3} =2\frac{1}{3}[/tex]

Note that [tex]\frac{AX}{AB}=\frac{6}{24} =\frac{1}{4} ,and\frac{AY}{AC}=\frac{10}{35}=\frac{2}{7}.[/tex]

Can someone please explain this to me?
Answer:
62°
Step-by-step explanation:
Angle KPO = 90°. If you add angles KPN and NPO together, you will get 90°. Set up an equation and solve for x.
2x + x - 3 = 90
3x - 3 = 90
3x - 3 + 3 = 90 + 3
3x = 93
3x/3 = 93/3
x = 31
Now solve for the measure of KPN by substituting 31 for x.
KPN = 2x
KPN = 2(31)
KPN = 62°
