Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67
Step-by-step explanation:
Conversion a mixed number 7 3/4
to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4
To find a new numerator:
a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4
b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31
c) Write a previous answer (new numerator 31) over the denominator 4.
Seven and three quarters is thirty-one quarters
Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/
100 = 767/100
1/2^-2 Can be written as 2^2
Therefore , 2×2=4
Answer:
one solution
Step-by-step explanation:
it has one solution because the slopes of the two equations(1x & 2x) are different, which means the lines of the two equations are not parallel, they have an intersection point(also means one solution).
Answer:
sqrt of 2/2
Step-by-step explanation:
Answer:
z=34
Step-by-step explanation:
2 + 8 - z = -24
add
10-z = -24
subtract 10 from each side
10-z-10 = -24-10
-z = -34
multiply by -1
-1*-z = -34 * -1
z = 34
