Answer: 1. -11=x 2. 24=x 3. x=-12 4. -7 5. x=7


Step-by-step explanation: The answer to first one can be calculated by seeing the - as a -1.

-5 = x - (-6)

-5=x+6

Then subtract 6 from both sides.

-5=x+6

-11=x

The answer to the second can be found simply by dividing both sides by 1.25.

- 30=1.25x

-30/1.25=1.25x/1.25

24=x

The third one can be solved by as we said before dividing both sides by -6.

-6x=72

-6x/-6=72/-6

x=-12

The fourth one can be found again by using division on both sides.

-4.9=0.7x

-4.9/0.7=0.7x/0.7

-7=x

Finally we solve the last one by again doing the same thing dividing both sides by 0.45.

3.15=0.45x

3.15/0.45=0.45x/0.45

7=x

Hope this helps!

What is the answer to -104=8x how do you find what x is
dybincka [34]
8x = -104 (I like to flip mine around like this, but it doesn't matter).
Now, you subtract 8 from both sides because you are doing the inverse.
-104 - 8 = -112
x=-112
Hope this helps!
Have a nice day!

Drag each measure to a box on the right to match the measure on the left. 5 feet10,560 feet48 inches126 inches 2 miles 123 yards
charle [14.2K]

Answer:

4 feets = 48 inches

2 miles = 10,560 feets

1 2/3 yards = 5 feets

3 1/2 yards = 126 inches

Step-by-step explanation:

Recall :

1 Feet = 12 inches

1 MILE = 5280 feets

1 yard = 36 inches

1 yard = 3 feets

If 1 feet = 12 inches

4 feets will be ; (12 * 4) inches = 48 inches

If 1 mile = 5280 feets

2 miles will be ; (5280 * 2) = 10,560 feets

If 1 yard = 3 feets

1 2/3 yards will be ; (5 /3) * 3 = 5 feets

If 1 yard = 36 inches

3 1/2 yards will be ; (7 /2 ) * 36 = 126 inches

Help me please I need the answer ASAP
ozzi

a

10.95x + 2.50, but for eight books so 10.95 x 8 + 2.50 = 90.10

b

12.50x + 4.50, but for six books so 12.50 x 6 + 4.50 = 79.50

c

To do this, we can set them both equal to each other and if x is a whole number of books, then they do pay the same amount. If x is a decimal, then they don't pay the same amount.

10.95x + 2.50 = 12.50x + 4.50

2.50 - 4.50 = 12.50x - 10.95x

-2 = 1.55x

This can never be a whole number, so therefore members and non-members can never pay the same amount for an order of x books.

DENIUS [597]
The number of situps form an AP with first term (a) = 17 and common difference (d) = 4

Tn = a + (n - 1)d
T12 = 17 + (12 - 1) x 4 = 17 + 11(4) = 17 + 44 = 61

Therefore, she will do 61 situps on day 12.
