Answer:
15
Step-by-step explanation:
cross multiplying, [tex]\frac{1}{5}[/tex] × [tex]\frac{3}{x}[/tex]
then it would be 15 =1x
and 1x is basically just one, so 15 = x
subtract the sum of 12ab-10b²-18a² and 9ab+12b²+14a² from ab+2b² and 3b²-a²
Answer:
3a² + 3b² - 20ab
Step-by-step explanation:
Sum of 12ab-10b²-18a² and 9ab+12b²+14a²
12ab - 10b² - 18a² + 9ab + 12b² + 14a²
= 14a² - 18a² + 12b² - 10b² + 12ab + 9ab
= -4a² + 2b² + 21ab
Sum of ab + 2b² and 3b²- a²
= ab + 2b² + 3b²- a²
= -a² + 2b² + 3b² + ab
= -a² + 5b² + ab
Subtract
-a² + 5b² + ab - (-4a² + 2b² + 21ab
)
= -a² + 5b² + ab + 4a² - 2b² - 21ab
= 3a² + 3b² - 20ab

a. The equation will be of the form x(x+2) = 80.
b. The two numbers are 8 and 10.
What is an integer ?An integer is a number which has no decimal value.
According to the given question we have to write an equation representing the fact the product of two consecutive even integers is 80.
Let us represent the smaller integer x and the greater integer by (x+2).
As even numbers comes after every 2 digits.
∴ x(x+2) = 80
x² + 2x = 80
x² + 2x - 80 = 0
x² + 10x - 8x - 80 = 0
x(x+10) - 8(x+10) = 0
(x+10) = 0 OR (x-8) = 0
x = -10 OR x = 8. ( x = 8 is the valid option as it satisfies the given equation)
The two integers are 8 and 10.

Step-by-step explanation:
Suppose y varies directly with x, and y=98 when x=14. Write the direct
variation equation that relates x and y.
===========================================================
Explanation:
Since y varies directly with x, this means y = kx for some constant k.
Plug in y = 98 and x = 14 to solve for k
y = kx
98 = k*14
98/14 = k
7 = k
k = 7
Therefore, y = kx updates to y = 7x which is the equation we're after.
Answer:
y = 7x
Step-by-step explanation:
The general formula for direct variation is y = kx, where k is the constant of proportionality. If y = 98 when x = 14, then k must be 98/14. or 7, and so
y = 7x is the desired direct variation equation.

The unit rate for peaches is $2.00 per pound. The unit rate for grapes is $2.50 per
pound. If you had $10 to spend, would you be able to buy a greater weight of
peaches or of grapes? Explain your answer.
Answer: A greater weight of peaches will be bought
Step-by-step explanation:
The unit rate for peaches = $2.00 per pound.
The unit rate for grapes = $2.50 per
pound.
Amount to spend = $10
Weight of peaches to buy with $10 = $10 / $2.00
= 5 pounds
Weight of grapes to buy with $10 = $10 / $2.50
= 4 pounds
Therefore, a greater weight of peaches will be bought as 5 pounds will be bought instead of 4 pounds for grape.
