Answer:
21 cats
Step-by-step explanation:
Since there are two variables and two sets of data, you can set up a system of equations and use the method of subsitution to solve for a variable which can then be substituted into the other equation.
First equation: 4c + 4.5d = 147 where c = cats and d = dogs
Second equation: c + d = 35
Solve for d in the second equation: d = 35 - c
Substitute the expression '35 - c' in for 'd' in the first equation:
4c + 4.5(35 - c) = 147
Distribute: 4c + 157.7 - 4.5c = 147 or 157.5 - 0.5c = 147
Subtract 157.5 from both sides: 157.5 - 157.5 - 0.5c = 147 - 157.5 or -0.5c = -10.5
Divide and solve for c: -0.5c/-0.5 = -10.5/-0.5 or c = 21 cats
Answer:
I think the answer is A if my math is wriye
Step-by-step explanation:
Answer:
area of square=36m²
area of square= side²
36cm²=side²
(36cm²)½=side
6cm=side
perimeter of square=4×side
perimeter of square =4×6cm
perimeter of square =24cm
33 * 5.15 = 169.95. 33 hours at 5.15 per hour
If you would like to calculate - 5 * g - 6 for g = -2, you can do this using the following steps:
- 5 * g - 6 = - 5 * (- 2) - 6 = 10 - 6 = 4
g = -2
The correct result would be A. 4.
