Remember the addition sign must be included for the equation to be valid.
Solve for the unknown:
-2(3 + 7h) + 2 = 108
Answer:
h = -8
Step-by-step explanation:
-2(3 + 7h) + 2 = 108
-2 * 3 + -2 * 7h + 2 = 108
combine like terms
-6 - 14h + 2 = 108
-4 - 14h = 108
add 4 to both sides of the equation
-4 + 4 - 14h = 108 + 4
-14h = 108 + 4
-14h = 112
divide both sides of the equation by -14
-14h/-14 = 112/-14
h = 112/-14
h = -8

The first step in solving this problem is to _________________ on each side of the equation. LaTeX: \frac{1}{4}x\:=\:-101 4 x = − 10
Answer:
multiply both sides by 4
Step-by-step explanation:
Given the expression
1/4 x = -10
The first step is to multiply both sides by 4 using the multiplicative property of equality
1/4 x * 4 = -10 * 4
x * 1 = -40
x = -40
Hence the first step is to multiply both sides by 4

PLEASE HELP ASAP (grade 8 question)
Answer:
Probably 80* (* means degrees for me) i might be wrong
Step-by-step explanation:
So if m<1 = 50* and m<2 = 65, then there might be a pattern.
50 + 15 = 65. So if 65 + 15 = 80, then 80* MIGHT be the answer.

How do I round 2726.821341 to the nearest cent
Answer:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.

Rounding calculator to round numbers up or down to any decimal place. Choose ones to round a number to the nearest dollar. Choose hundredths to round an amount to the nearest cent.
Rounding Numbers
Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:
Rounding to the nearest hundred is 800
Rounding to the nearest ten is 840
Rounding to the nearest one is 838
Rounding to the nearest tenth is 838.3
Rounding to the nearest hundredth is 838.27
Basic Rules of Rounding
When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:
Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.
Round to the Nearest Hundred: 3250
Identify the hundreds digit: the 2 in 3250
Identify the next smallest place value: the 5 in 3250
Is that digit greater than or equal to five? Yes, so round up.
Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.
3250 rounded to the nearest hundred is 3300
Round to the Nearest Ten: 323.5
Identify the tens digit: the 2 in 323.5
Identify the next smallest place value: the 3 in 323.5
Is that digit greater than or equal to five? No, so round down.
The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.
323.5 rounded to the nearest ten is 320
Round to the Nearest Ten: 499
Identify the tens digit: the first 9 in 499
Identify the next smallest place value: the second 9 in 499
Is that digit greater than or equal to five? Yes, so round up.
The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.
499 rounded to the nearest ten is 500
Round to the Nearest Tenth: 0.74
Identify the tenths digit: 7 in 0.74
Identify the next smallest place value: the 4 in 0.74
Is that digit greater than or equal to five? No, so round down.
The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.
0.74 rounded to the nearest tenth is 0.7
Round to the Nearest Hundredth: 3.141
Identify the hundredths digit: the 4 in 3.141
Identify the next smallest place value: the second 1 in 3.141
Is that digit greater than or equal to five? No, so round down.
The hundredths digit stays the same at 4. Drop the digits to the right of 4.
3.141 rounded to the nearest hundredth is 3.14
