Solve 4 1/4 - 2 11/20

Answers

Answer 1

Answer: $4(1)/(4) - 2(11)/(20)$
Change them into improper fractions by multiplying the denominator(bottom) by the whole number then adding the numerator
$(17)/(4)$ - $(51)/(20)$
You must have a common denominator
Multiply $(17)/(4)$ by $(5)/(5)$ ⇒ $(85)/(20)$
$(85)/(20)$ - $(51)/(20)$ = $(34)/(20)$
Simplify by dividing the numerator by the denominator
34÷20= $1(14)/(20)$ ⇒ $1 (7)/(10)$ reduced
You answer is $1 (7)/(10)$

Answer 2

Answer: This could be solved as a group of mixed numbers, but I like to work with improper fractions more.
17/4 - 51/20
Next, you need to find a common denominator.
85/20 -51/20
When adding and subtracting fractions, you only work in the numerator, and the denominator stays the same.
34/20
Then, you just simplify.
Improper fraction: 17/10
Mixed number: 1 7/10
Decimal: 1.7

A cheetahs sprinting speed is 61 miles per hour less than three times a zebras running speed. A cheetah can sprint 68 miles per hour. Find the zebras running speed

Answers

Let Cheetah speed be c, let Zebra speed be z

Cheetah speed is (=) 61 miles per hour less than 3 * zebra running speed.

c = 3z - 61.

c = 68 miles/hour

c = 3z - 61

68 = 3z - 61

3z - 61 = 68

3z = 68 + 61

3z = 129

z = 129/3

z = 43

Zebra speed is 43 miles per hour

Solve the system using elimination.
3x + 5y = 55
5x + 4y = 57

Answers

Answer:

x=5, y=8. (5, 8).

Step-by-step explanation:

3x+5y=55

5x+4y=57

---------------

5(3x+5y)=5(55)

-3(5x+4y)=-3(57)

-------------------------

15x+25y=275

-15x-12y=-171

---------------------

13y=104

y=104/13

y=8

3x+5(8)=55

3x+40=55

3x=55-40

3x=15

x=15/3

x=5
