Answer:
Step-by-step explanation:
10x+10y=-10
9x+10y=18
= 10x+10y=-10
-9x-10y=18
= x=8
step two is to find y:
10x+10y=-10
10(8)+10y=-10
80+10y=-10
10y=-90
y=-9
your answer:
(x,y)= (8,-9)
Answer:
378 cm^3
Step-by-step explanation:
V = Bh = l * w * h
since the Base B is 54 (l*w), multiply by 7 to find volume
54 * 7 = 378

Step-by-step explanation: The slope-intercept form is
y
=
m
x
+
b
y
=

Answer:
40.0
18%
14.375%
1/250
38
6325
Step-by-step explanation:
Convert the percent to a decimal 4,000%
4000% = 4000/100 = 40.0
Convert the decimal or whole number to a percent.
0.36 * 1/2
= 0.36/2 * 100
= 0.18 * 100
= 18%
Convert the decimal or whole number to a percent.
1.15 * 1/8
= 1.15/8 * 100
= 14.375%
Convert the percent to a reduced fraction, mixed number, or whole number.
0.4%
= 0.4/100
= 1/250
Solve for the portion (in $). Round to hundredths when necessary.
9 1/2% of $400 = 19/2% x 400
= 0.095 x 400
= 38
Solve for the portion. Round to hundredths when necessary.
What number is 253% of 2,500?
253/100 x 2500
= 2.53 x 2500
= 6325
