Answer:
cab=62
cba=48
x=12
Step-by-step explanation:
70+x+50+4x=180
combine like terms
120+5x=180
-120. -120
5x= 60
isolate x
5x=60
x=12
Answer:
Step-by-step explanation:
3/8n +1=-25
3/8n=-26
3/8n*8/3n=-26 divide 8/3n
n=-39/4
$1.35 x 10 = $13.50 for 10 gallons
$23.50 - $13.50 = $10.00
$1.35 x 7 = $9.45 for 7 more gallons
17 gallons is $22.45
17/27 = 459 miles but I'm missing the last bit of change so round it up to 460 for a total of miles
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
Answer:
15
Step-by-step explanation:
if 6/10 = 9 gal. then we can divide 9 by 6 and then multiply that answer by ten
