Answer:
7+p
Step-by-step explanation:
More than means add
a number means x, in this case it's p
Answer:
x = -2, y = 2
Step-by-step explanation:
-7x + 7y = 28
7y = 28 + 7x
y = 4 + x ----(1)
-8x+4y=24 -----(2)
sub (1) into (2)
-8x+4(4+x)=24
-8x+16+4x = 24
-8x+4x = 24-16
-4x = 8
x = -2
sub x = -2 into (1)
y=4+(-2) = 2
Answer:
110 and 70
Step-by-step explanation:
opposite sides of parallelograms are equal so you can set 2x+30 equal to 5x-90
when you do this:
2x+30=5x-90
-2x -2x
30=3x-90
+90 +90
120=3x
/3 /3
40=x
now you can plug 40 in for 5x-90
example:
5(40)-90
200-90
110
m<r=110
<r and <s are supplementary because they are consecutive angles
supplementary is when two angles add up to 180
since <r is 110, do 180-110 and get 70
m<s = 70
