Answer:
Option 3 - The value of c is 3.
Step-by-step explanation:
Given : If 32 Superscript 2 c Baseline = 8 Superscript c + 7.
To find : What is the value of c?
Solution :
Superscript denotes the power.
32 Superscript 2 c i.e. 
8 Superscript c + 7 i.e. 
The equation form is 
.
Write the expression as,
Comparing the base,
Therefore, the value of c is 3.
So option 3 is correct.
The answer to the above question is three
Lets look at the info we have:-
1 pound of cheese = $6.75
2.6 pounds of cheese
MULTIPLY TO FIND D ANSWER:-
$6.75 × 2.6 = $17.55
2.6 pounds of cheese cost $17.55.
CHECK OUR WORK:-
17.55 ÷ 2.6 = 6.75
we were RIGHT!!
So, 2.6 pounds of cheese costs $17.55.
Hope I helped ya!! xDc
Answer:
12
Step-by-step explanation:
(x-1)+(y+1)+(z-1)
= x -1 + y + 1 + z - 1
= x + y + z -1
= (x + y + z) -1
given that x+y+z = 13, substitute this value into the equation aove
(x + y + z) -1
= 13 - 1
= 12
Answer:
30 revolutions
Step-by-step explanation:
to calculate the revolution of the wheels in 66 metres we need to get the circumference
circumference = 2πr, r = radius (diameter divided by 2) but from the formula of circumference we ca rewrite it as πd= 3.14 x 70 = 219.8cm
next convert 66 metres to cm
100cm = 1m
x= 66m
cross multiply
x= 66m x100cm/1m= 6600cm
revolutions in 66metres = 6600cm/219.8cm = 30.0272975 ≅30 revolutions
