Answer:
Please check the explanation.
Step-by-step explanation:
Considering the expression
[tex]9i+2\left(7+3i\right)[/tex]
Applying the distributive law[tex]a\left(b+c\right)=ab+ac[/tex]
so the expression becomes
[tex]=9i+2\cdot \:\:\:7+2\cdot \:\:\:3i[/tex]
Group like terms
[tex]=9i+14+6i[/tex]
Add similar elements: 9i+6i=15i
[tex]=15i+14[/tex]
With the equation 3x - 5 = x + 3,
Answer:
x = 4 :)
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
3x - 5 = x + 3
add 5 to both sides
3x = x + 8
subtract x from both sides
2x = 8
divide both sides by 2
x = 4

What are the solutions to the equation 3x2 + 10x = 8
Answer:
(3x-2)(X+4)
X=2/3,-4
Step-by-step explanation:
3x^2 + 10x = 8
3x^2+12x-2x-8=0
3x(X+4)-2(X+4)=0
(3x-2)(X+4)=0
X=2/3,-4
So the solution is 2/3,-4

what is 4 divided by 0.576
4 divided by 0.576 is approximately equal to 6.9444.
To find the result of 4 divided by 0.576, we can perform the division by dividing the numerator ( 4 ) by the denominator ( 0.576 ).
When we divide 4 by 0.576, we get approximately 6.9444.
Therefore, 4 divided by 0.576 is approximately equal to 6.9444.
In decimal form, this indicates that 4 can be divided into 0.576 approximately 6.9444 times. The result is a decimal number that extends to multiple decimal places. To obtain a more precise or exact answer, additional decimal places may need to be considered in the calculation.

A patio 44, feet wide is being constructed next to a house. To drain water off the patio and away from the house, a slope of 1/2 inch per foot is necessary. What total
difference in height is required from one edge of the patio to the other?
Answer:
the total difference in height will be 22 inches
Step-by-step explanation:
since the slope is 0.5 inch per foot, and the patio is 44 feet wide, the end of the patio will be 0.5 x 44 = 22 inches lower
the slope measures how much the height (Y axis) will change as the length (X axis) increases by 1 unit. In this case, since the height decreases as the length increases the slope is negative.
1) Fairview and Abbots Rise are 5 in apart on a map that has a scale of 1 in : 18 mi. How far apart are the real cities? 2) A particular satellite is 12 ft wide. A model of it was built with a scale of 1 in :3 ft. How wide is the model? Please help me I have 4 more questoins
Answer:
1) 90 mi
2) 4 inch
Step-by-step explanation:
1)
Given that the distance between Fairview and Abbots Rise on the map = 5 in
Scale of the map = 1 in: 18 mi
i.e. 1 inch on map is equivalent to an actual distance equal to 18 mi between the cities.
Given that the map has a distance of 5 inches.
Therefore, the actual distance between the cities = 5 [tex]\times[/tex] 18 = 90 mi
2) A particular satellite is 12 ft wide.
Model's scale = 1 in : 3 ft
i.e. 1 inch on map is equivalent to actual distance of 3 ft.
OR
3 ft of actual distance = 1 in on map
1 ft of actual distance = [tex]\frac{1}{3}[/tex] in on map
12 ft of actual distance = [tex]\frac{1}{3}\times 12 = \bold{4\ inch}[/tex]

A swimming pool has two pipes coming into it to fill it with water. One pipe takes 16 hours to fill it. The other takes 12 hours to fill it. How many hours will it take both pipes to fill the pool?
Answer:
8 hours
Step-by-step explanation:
8 hours because half of 16 is 8 and half of 12 is 6
If it takes 6 hours to fill one half then the other 2 hours would go to the other pipe making it 8 hours
The cash price of a laptop is $1299. It can be bought at hire purchase by making a deposit of $350 and 10 monthly payments at $120 each.
(i) What is the TOTAL hire purchase
(ii) How much is saved by buying the laptop for cash
I) The TOTAL hire purchase of the laptop is; $1550
II) The amount saved by buying the laptop for cash is; $251
I) We are told that the laptop can be bought at hire purchase by making a deposit of $350 and 10 monthly payments at $120 each.
Thus;
Cost of laptop by hire purchase = 350 + 120(10)
>> 350 + 1200
>> $1550
II) Since the cash price is $1299, then amount saved = 1550 - 1299
>> $251

Bob paid $5.60 for 0.8 lb of fresh peaches.
How much would 3.25 lb of peaches cost?
Answer:
22.75
Step-by-step explanation:
5.6 divided by 0.8=Constant Variation=7
3.25*7=22.75
The price of the 3.25 lb peaches is $22.75.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Bob paid $5.60 for 0.8 lb of fresh peaches. The price of the 3.25 lb peaches will be calculated as,
0.8 lb of peaches ⇒ $5.60
1 lb of peach ⇒ $5.60 / 0.8
3.25 lb of peaches ⇒ (3.25 x $5.60 ) / 0.8
3.25 lb of peaches ⇒ $22.75
Therefore, the price of the 3.25 lb peaches is $22.75.

The ratio x : y is equal to 2 : 5, and y is 80% of z. Write an equation to represent the proportional relationship between x and z.
Answer:
x : z = 8 : 25Step-by-step explanation:
Given
x : y = 2 : 5, y is 80% of zRearranging the ratios:
x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5xy is 80% of z ⇒ y = 0.8zComparing the values of y:
2.5x = 0.8zx/z = 0.8/2.5x/z = 0.32x/z = 32/100 x/z = 8/25x : z = 8 : 25Write the slope- intercept form of the equation of the line described through (4,5) parallel to y= 1/4x-4
Answer:
y = 1/4 x + 4
Step-by-step explanation:
1. Because the new equation is parallel to y= 1/4x - 4 => the slope is still the same => New equation : y = 1/4x + b ( b is a number that we'll find now)
2. Put x = 4 and y = 5 in the new equation
=> 5 = (1/4)(4) + b
=> b = 4
3. So then we'll have the new equation that is parallel to y = 1/4x-4
