Answer:
x=\frac{64}{5}=12\frac{4}{5}
Step-by-step explanation:
1. Simplify the expression
\frac{-1}{4}\cdot\left(x+\frac{12}{3}\right)=\frac{+\left(-21\right)}{5}
Find the greatest common factor of the numerator and denominator:
\frac{-1}{4}\cdot\left(x+\frac{\left(4\cdot3\right)}{\left(1\cdot3\right)}\right)=\frac{+\left(-21\right)}{5}
Factor out and cancel the greatest common factor:
\frac{-1}{4}\cdot\left(x+4\right)=\frac{+\left(-21\right)}{5}
Multiply the fractions:
\frac{\left(-1\cdot\left(x+4\right)\right)}{4}=\frac{+\left(-21\right)}{5}
Expand the parentheses:
\frac{\left(-x-4\right)}{4}=\frac{+\left(-21\right)}{5}
Break up the fraction:
\frac{-x}{4}+\frac{-4}{4}=\frac{+\left(-21\right)}{5}
Find the greatest common factor of the numerator and denominator:
\frac{-x}{4}+\frac{\left(-1\cdot4\right)}{\left(1\cdot4\right)}=\frac{+\left(-21\right)}{5}
Factor out and cancel the greatest common factor:
\frac{-x}{4}-1=\frac{+\left(-21\right)}{5}
Answer:
The answer is x= 7 2/15. So the third one.

A child has 12 blocks, of which 6 are black, 4 are red, 1 is white and 1 is blue. All blocks of the same color are identical. If the child puts the blocks in a line, how many arrangements are possible?
Answers
The arrangement of the blocks is an illustration of permutation and combination
The number of possible arrangement is 27720 ways
How to determine the number of arrangementsThe given parameters are:
n = 12
Black = 6
Red = 4
White = 1
Blue = 1
The number of possible arrangement is then calculated as:
[tex]Ways = \frac{12!}{6!4!1!1!}[/tex]
Evaluate the factorials

Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°

Which step could be used to help isolate the variable in the following equation? 5. 6j – 0. 12 = 4 1. 1j.
Answers
For the expression 5.6j - 0.12 = 4 + 1.1j, the value of variable j is 0.92.
What is the property of equality?
The operations of addition, subtraction, multiplication, and division do not change the truth value of any equation is called the property of equality.
The given expression is 5.6j - 0.12 = 4 + 1.1j.
To solve the above expression, we will use the following steps.
Step 1:
By the subtraction property of equality, subtract 1.1j on both sides. We get the expression,
[tex]5.6j - 0.12 -1.1j = 4 + 1.1 j - 1.1 j[/tex]
[tex]4.5 j -0.12 = 4[/tex]
Step 2:
By the addition property of equality, add 0.12 on both sides. We get the expression,
[tex]4.5j -0.12 + 0.12 = 4 + 0.12[/tex]
[tex]4.5 j = 4.12[/tex]
Step 3:
By the division property of equality, divide the above expression by 4.5. We get the expression,
[tex]\dfrac {4.5j}{4.5 }= \dfrac {4.12}{4.5}[/tex]
[tex]j = \dfrac {4.12}{4.5}[/tex]
[tex]j = 0.92[/tex]
Hence we can conclude that the value of variable j is 0.92.

D. 60°
Step-by-step explanation:
The interior angles of all triangles add up to 180 degrees.
There are two y's on the triangle
And one of the degree lengths is 60°, so we do:
2y + 60 = 180
Subtract 60 from both sides
2y + 60 - 60 = 180 - 60
2y = 120
Divide 2 from both sides
2y/2 = 120/2
y = 60°
Also, In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
All three sides are equal
All the three interior angles are equal to 60 degrees
The interior angles of all triangles add up to 180 degrees.

Given,GRAM is a parallelogram m<GMA = 66°m<GRP = 32°m<PAM = 41°Solutions:i) Since,
Angles on the same side of a transversal in a parallelogram, there sum is 180° so,
<RGM + <GMA = 180°
=> <RGM = 180° - <GMA
=> <RGM = 180° - 66°
=> <RGM = 114° (Ans)
ii) Since,
Opposite angles of a diagonal as a transversal (here RM) are equal so,
<GRP = <PMA = 32°
As we have <GMA = 66° so,
=> <GMP = <GMA - <PMA
= 66° - 32°
=> <GMP = 34° (Ans)
iii) Since,
Opposite angles of a parallelogram are equal so,
<RGM = <RAM = 114°
As we have <PAM = 41° so,
=> <GAR = <RAM - <PAM
= 114° - 41°
=> <GAR = 73° (Ans)
iv) Since,
We got <PMA = 32° and <PAM = 41°, so by angle sum property of a triangle PMA,
=> <MPA = 180° - 32° - 41°
=> <MPA = 107° (Ans)

What is the percentage of lemons in the is group of lemons and strawberries?
Answers
Answer:

Step-by-step explanation:
Total: 60
Strawberries: 18
Lemons: 42
[tex]\frac{42}{60}[/tex] = [tex]\frac{7}{10}[/tex] = 70%
The percentage of lemons in the group is equal to 70%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that in the image there are 60 objects in total, the number of lemons is 42 and the number of strawberries is 18.
Total: 60
Strawberries: 18
Lemons: 42
The percentage of the lemons will be calculated as,
Percentage = 42 / 60
Percentage = 0.7
Percentage = 0.7 x 100 = 70%
Therefore, the percentage of lemons in the group is equal to 70%.

Given the following data:
Radius A = 5 cm.Radius B = 3 cm.How to calculate the area of a circle.Mathematically, the area of a circle is given by the formula:
[tex]Area = \pi r^2[/tex]
Where:
r is the radius of a circle.For circle A:

Area = 78.55 [tex]cm^2[/tex].
For circle A:
[tex]Area = 3.142 \times 3^2\\\\Area = 3.142 \times 9[/tex]
Area = 28.278 [tex]cm^2[/tex].

Gina bought x cans of peas for $0.85 each and yvcans of corn for $0.78 each. She boguth 2 more cans of peas than cans of corn. The total was $6.59. How many cans of oeas and cans of corn dis she buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answers
Answer:
Step-by-step explanation:
Number of cans of peas = x
Cost of 'x' cans of peas = x *0.85 = 0.85x
Number of cans of corn = y
Cost of 'y' cans of corn = 0.78*y = 0.78y
Number of cans of peas = number of cans of corn + 2
x = y + 2 --------------(I)
x - y = 2 ----------------(II)
Total cost = $ 6.59
0.85x + 0.78y = 6.59 -------------(III)
Substitute x = y +2 in equation (III)
0.85(y + 2) + 0.78y = 6.59
0.85y + 1.70 + 0.78y = 6.59
0.85y + 0.78y = 6.59- 1.70
1.63y = 4.89
y = 4.89/1.63
y = 3
Number of cans of corn = 3
Plugin y = 3 in equation (I)
x = 3 + 2
x = 5
Number of cans of peas = 5
