4,-2
distribute and combine like terms
Answer:
(4, -2)
Step-by-step explanation:
7x+3y= 22
3x-3y= 18
Add them in vertical columns. 7x + 3x = 10x. The 3y and the -3y cancel each other out. 22+ 18 = 40.
You're left with 10x = 40. Solve for x by dividing both sides by 10
x = 4
Plug in 4 into any of the original equations and solve for y.
7(4) + 3y =22.
28 + 3y =22
Subtract 28 on both sides
You're let with 3y = -6. Solve for y by dividing both sides by 3
y= -2
Put it together in coordinate point form. (4, -2)

Dans mother bought a car for 15,000 five years ago. She wants to sell it to Dan based on 12% annual rate of depreciation. At this rate, how much will Dan pay for the car?
Step-by-step explanation:
= P [ 1-R/100 ] T
= 15000 [ 1-12/100] ⁵
= 15000 [100-12/100]⁵
= 15000 [0.88]⁵
= 15000 × 0.52773
= 7915.95..
i hope it's correct....

The smelter produces 384 tons of cast iron a day. How much coke is burned per day during smelting if 15 tons of coke is consumed per 16 tons of cast iron?
Answer:
360 tons
Step-by-step explanation:
Coke burned : cast iron = 15 : 16
The smelter produces 384 tons of cast iron a day
Let x = tons of coke burned
Coke burned : cast iron = x : 384
Equate both ratios
15 : 16 = x : 384
15/16 = x/384
Cross product
15 * 384 = 16 * x
5,760 = 16x
x = 5,760/16
x = 360
x = tons of coke burned = 360 tons

Which expression represents the volume of the prism? One-halfx3 (one-half x) cubed Five-halvesx3 (Five-halves x) cubed
Answer:
Volume = ½x³ units.
Step-by-step explanation:
From the image, we can deduce the following;
Length = x
Breadth = x
Height = ½x
To find the volume of prism;
Mathematically, the volume of a prism is given by the formula;
Volume of prism = length * breadth * height
Substituting into the formula, we have;
Volume of prism = x * x * ½x
Volume = x² * ½x
Volume = ½x³ units

The surface area of a triangular prism is 18: square inches. What is the surface area of a similar solid that has been enlarged by a scale factor of 2.52?
Answer:
45.36 square inches
Step-by-step explanation:
Given the following
Surface area of a triangular prism = 18 square inches
If it is enlarged by a scale factor of 2.52, the area of the enlarged solid is expressed as;
Area of enlarged solid = area of original sold * scale factor
Area of enlarged solid = 18 * 2.52
Area of enlarged solid = 45.36 square inches
hence the surface area of a similar solid that has been enlarged by a scale factor of 2.52 is 45.36 square inches
Answer:45.36 square inches

A shirt was sold for sh 1054 after a 15% discount . what was the discount given
Answer: discount was 186
Step-by-step explanation: original price is x.
15 % = 0.15x , and x -0.15x= 1054 and 0.85x = 1054
Then x = 1054/0.85 = 1240. Discount was 1240-1054 = 186

Answer:
678.4 cm^2
Step-by-step explanation:
total surface area of prism is equal to ph+2B where p represents the perimeter of the base, h the height of the prism and B the area of the base.
Firstly, we calculate the perimeter of the base. This is equal to 10 + 14 + 10 + 14, or 48.
Secondly, we must calculate the height of the prism, which is shown as 8.3.
Lastly, we must calculate the area of the base, which is 10 * 14, or 140.
We can now substitute these values into the formula, ph + 2B to find the total surface area of the prism:
ph + 2B,
(48)(8.3) + 2(140),
398.4 + 280,
678.4
This means that the total surface area of this prism is 678.4 cm^2

Denise earns $4,500 per month plus 4% commission on her sales. One month she had sales of $50,000. What were her total earnings? • a. $50,000 • b. $2,000 • c. $6,500
Answer:
$6500
Step-by-step explanation:
Given data
Monthly Earnings= $4500
Commission= 4%
Sales= $50000
Let us find the amount of the commission
=4/100*50000
=0.04*50000
= $2000
Since the monthly earning is $4500, hence the total earning is
=2000+4500
=$6500

-8 = 6 - 14
use the number line:
go to 6 on the number line and count back until you reach -8; you should count 14
since it's a -8 that means the bigger number also has to be negative. between 6 and 14, 14 is bigger so it becomes a negative number
so your answer is -14
