We would take the length and width of the patio and subtract it by the area that does not need to be painted.
I got this right on the test!
Answer:
Area = 5(x + 4y - 6).
Step-by-step explanation:
The area of the whole figure = area of rectangle + area of the triangle
= 10(2y - 3) + 1/2 * 10 * x
= 20y - 30 + 5x
= 5(x + 4y - 6).
Answer:
1+1-1*1/1=1
Step-by-step explanation:
1+1-1*1/1=1
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:
(5/14) * x = 90
x = 252
Number of R5 coins = (2/14) * 252 = 36
Number of R1 coins = (7/14) * 252 = 126
Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,
