Answer:
no, ann is incorrect. each week is a new 3 pushups so by the 15th week, barry would have done 58 pushups.
Step-by-step explanation:
Answer:
8.57
Step-by-step explanation:
y=AC
7/15=11/y
y=23.57
x=y-15
x=8.57
Answer:
33 °C
Step-by-step explanation:
Put 92 where F is in the equation, and solve for C.
92 = 1.8C +32 . . . . substitute for F
60 = 1.8C . . . . . . . . subtract 32
60/1.8 = C ≈ 33.33 ≈ 33 . . . . . divide by the coefficient of C, round the result
The temperature is about 33 °C.
The sum of the angles of a triangle is 180°. So you can do:
91° + (8x + 3)° + (10x - 4)° = 180° To find x, you need to isolate/get the variable "x" by itself in the equation. First combine like terms (terms that have the same variable and power/exponent]
91 + 3 - 4 + 8x + 10x = 180 (I rearranged for the like terms to be next to each other)
90 + 18x = 180 Subtract 90 on both sides
18x = 90 Divide 18 on both sides to get "x" by itself
x = 5
PROOF
91° + (8x + 3)° + (10x - 4)° = 180° Plug in 5 for "x"
91° + (8(5) + 3)° + (10(5) - 4)° = 180°
91° + (40 + 3)° + (50 - 4)° = 180°
91° + 43° + 46° = 180°
180° = 180°
- 12. What do you mean by that question? -12 itself is an integer.
