Answer:
(-3, -2)
Step-by-step explanation:
Look at the second equation, we can easily rearrange it to make x the subject.
x - 4y = 5
x = 4y + 5
Now lets put that into the second equation
2x - 2y = -2
2(4y + 5) - 2y = -2
6y + 10 = -2
6y = -12
y = -2
Now lets find x!
x = 4y + 5
x = 4(-2) + 5
x = -3
Now lets format the answer like the question says (ordered pair)
(-3, -2)
Recap: We used substitution and made an equation to work out one of the variables first, then found the second variable using the first.
Answer:
49 cm²
Step-by-step explanation:
Formula for area:
a = l (length) x w (width)
if its 7 cm on each side, then the length and width will be 7
7*7 = 49 cm²
Answer:
3/4 is what you are adding
17/4+3/4=20/4=5
10 ×10 = 100
100 ×25 = 2500
so your answer is 2500
