Answer:

=-1\frac{1}{2}

Step-by-step explanation:

Given the following question:

-3\frac{3}{4} \div2\frac{1}{2}

In order to find the answer, we first convert the mixed numbers into improper fractions. Then we use KCF (Keep, Change, Flip) and solve.

-3\frac{3}{4} \div2\frac{1}{2}
-3\frac{3}{4} =12+3=-\frac{15}{4}
2\frac{1}{2}=2\times2=4+1=\frac{5}{2}
-\frac{15}{4} \div\frac{5}{2}
-\frac{15}{4} \times\frac{2}{5}
15\times2=30
4\times5=20
=-\frac{30}{20}
-\frac{30}{20} \div10=-\frac{3}{2}
-\frac{3}{2}=3\div2=-1\frac{1}{2}
=-1\frac{1}{2}

Hope this helps.

X + 4.2 = 7 what is x
ANEK [815]

In this question, you're solving for x.

Solve for x:

x + 4.2 = 7

You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:

x = 2.8

Answer:

x = 2.8
