Answer:

12.25

Step-by-step explanation:

Since 12 is increased by 25%

It means that 12+25%

Note that the increased means that 25% is added

So let's solve

12+25%

% means 100

12+(25/100)

12+0.25

12.25

So the final answer is 12.25

ΔACD and ΔASR are the same so we can write a ratio:

x/4 = 10/5

x/4 = 2

x/4 * 4 = 2 * 4

x = 8

Since AS is equal to x, they are both the same.

Therefore, the answer is [ x = 8, AS = 8 ]

Best of Luck!

+(-6) + (-8)= -4<br> What’s the missing number???
Darya [45]

Answer:

10

Step by step explanation:

In general, if we have an equation that has just one variable, such as x, then "solving the equation" means finding the set of all values that can be substituted for the one variable to produce a valid equation.

Isolate "x" on one side of the algebraic equation by adding the negative number that appears on the same side of the equation as the "x." For example, in the equation "x - 5 = 12", rewrite the equation as "x = 12 + 5" and solve for "x."

x + (-6) + (-8) = -4

x + (-6 + -8) = -4

x + (-14) = -4

x + (-14 + 14) = -4 + 14

x = 10
