Answer:
3×-6=3
3×=3+6
3×=9
×=3
Step-by-step explanation:
multiply 3 by the variables in the bracket.
then you will get 3×-6=3.
take the -6 to the right hand side and it becomes+6
then you get 3×=3+6 therefore =3×=9
then divide both sides by 3.
3×÷3 and 9÷3
×=3
Given :
Length of one of the equal sides of an isosceles triangle = 3x+2
Then, length of the other equal side will also be = 3x+2
Length of the unequal side of this isosceles triangle = 14
Formula for finding the perimeter of an isosceles triangle :

A formula for finding the perimeter of this isosceles triangle :

Bringing all like terms together we get :



Thus, the formula = 6x+18
Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
Answer:
Barry had the following:
8 bananas
12 apples
20 kiwi
32 peaches
8 grapefruit
4 mangos
88 total
Step-by-step explanation:
Each of the amounts of fruit can be written in terms of one variable. Starting with bananas as 'x', we can then make different values of 'x' to produce all the other numbers of fruits:
bananas = x
apples = 2x (twice as many bananas)
kiwi = 2.5x (5/6 of applies and bananas combined = 5/6(3x) or 2.5x)
peaches = 3.5x + 4 (sum of bananas and kiwis plus four = x + 2.5x + 4)
grapefruit = x (half as many apples = 2x/2)
mango = 0.5x (20% of kiwi = (0.2)(2.5)x)
88 = x + 2x + 2.5x + 3.5x + 4 + x + 0.5x
88 = 10.5x
8 = x (bananas)
apples = 2x or 16; kiwi = 2.5x or 20, peaches = 3.5x + 4 = 32, grapefruit = x or 8, mangos = 0.5x or 4
Answer:
Amy would have 2.15 left
Step-by-step explanation:
To find out how much she has left, subtract the cost of the items from 10.
10 - 0.75 - 5.50 - 1.60 = 2.15
