Answer:
x=130;
Step-by-step explanation:
70+(x-20)=180
-70 -70
x-20=110
+20 +20
x=130
Answer:
Put y as zero to get the x-intercept
x-intercept is (15/2,0)
Step-by-step explanation:
2x-5y=10
2x=5y+10
1. Put y as zero to get x-intercept
2x=15
x=15/2

Estimate the sum in two different ways:
A) By rounding off to the highest place value (hundreds):
368 = 400 (3 hundreds is the highest place value)
231 = 200 (2 hundreds is the highest place value)
400 + 200 = 600
B) By rounding off to the second highest place value (tens):
368 = 370
231 = 230
370 + 230 = 600
Hope this helps!
