The solution to an equation is 21
Answers
if you wanna know how to solve this
here is how:
Simplifying 2p + 7 = 21 Reorder the terms: 7 + 2p = 21 Solving 7 + 2p = 21 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2p = 21 + -7 Combine like terms: 7 + -7 = 0 0 + 2p = 21 + -7 2p = 21 + -7 Combine like terms: 21 + -7 = 14 2p = 14 Divide each side by '2'. p = 7 Simplifying p = 7

It means that your weight on moon will be 6 times less than on Earth.
Now we have to multiply 31lb which is weight of the person on moon by 6 to get his weight on Earth
Similarly if your mass on moon is 31 lbs then your mass on earth will be 31*6=186 lbs.

Step-by-step explanation:
2x + 5 = 4(9x - 11)
2x + 5 = 36x - 44
36x - 44 = 2x + 5
36x - 2x = 5 + 44
34x = 49
x = 49/34
Answer:
x=49/34
Step-by-step explanation:
1.) Multiply both sides by 4
(4) 2x+5/4 = 9x-11 (4)
2x+5 = 36x-44
2.) Subtract 2x from both sides
2x+5 = 36x-44
-2 -2
5 = 34x-44
3.) Add 44 to both sides
5 = 34x-44
+44 +44
49=34x
4.) Divide by 34
49/34 = 34x/34
x=49/34

432 ft^2
Step-by-step explanation:
Answer:
432
Step-by-step explanation:
Lets plug it into the formula
b1 should be the horizontal line on the bottom horizontal line and b2 should be the top horizontal line
so we get b1 = 28 and b2 = 20
according to the formula we should add b1 and b2, getting us 48.
divide 48 by 2: we get 24
24 times h, or the hieght, or 18 is 432
so the answer is 432

Fall 3°F to return to the initial temperature of 71°F so option (B) will be correct.
What is the arithmetic operator?
Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Initial temperature = 71°F
The temperature dropped 5°F = 71 - 5 = 66°F
Then rose of 8°F = 66 + 8 = 74°F
So,
The temperature has risen by 3°F so it needs to fall to match the initial temperature.
Hence "Fall 3°F to return to the initial temperature of 71°F".
