Answer:
x=m-z
Step-by-step explanation:
The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z
7 3/4 + 2 3/4 you can add
7 + 2 = 9.
3/4 + 3/4 = 6/4. That can simplify into 1 2/4 = 1 1/2.
The answer is 10 1/2.
You're welcome :)
Answer:
Step-by-step explanation:
Triangle A
Use Pythagorean theorem.
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25
x = √25
x = 5 cm
Triangle B:
y² = 12² + 5²
= 144+ 25
= 169
y = √169
y = 13

This one is deceiving my simple. Start with the ratio 2/3. To find more ratios that are proportionate, simply multiply the numerator and denominator by the same number. Let's go with 2. So, 2*2/2*3 (which is 4/6) should be equal to 2/3. If you plug both into a calculator, you will see that they both equal 0.667, and are therefore proportionate.
Here are some more examples:
2/3, 4/6, 6/9, 8/12, 10/15
