What is 4/5+1/4 ? In fraction form.

1 answer:

6 0

To answer this question you must make a come factor between the 2 fractions I believe the easiest way to do this is multiply the denominator or bottom number by the other one so 4*5 and 5*4 and what you do to the denominator you must do to the numerator so you would have to do 4*4 and 4*5 for the first fraction to get 16/20 and repeat on the other side 1*5 and 4*5 or 5/20 so the to fractions are 16/20+5/20 then add just the numerators 16+5=21 or 21/20 and simplify to 1/20

Zahara mixed 5 quarts of dry ingredients and 2 quarts of water to make a

krok68 [10]

Answer:

Zahara need to add 4 quarts of water to keep the consistency the same

Step-by-step explanation:

Let

x -----> the amount of dry ingredients in quarts

y -----> the mount of water in quarts

we know that

Batch 1

$\frac{x}{y}=\frac{5}{2}$

Isolate variable y

$y=\frac{2}{5}x$ ----> equation A

Batch 2

For x=10

substitute in the equation A and solve for y

$y=\frac{2}{5}(10)=4$

The ratio batch 2 is $\frac{10}{4}$

therefore

Which of the binomials below is a factor of this trinomial?

KiRa [710]

Answer:

D. x + 4

Step-by-step explanation:

<u>Let's factor the trinomial:</u>

x² + 14x + 40 =
x² + 4x + 10x + 40 =
x(x + 4) + 10(x + 4) =
(x + 4)(x + 10)

x + 4 is between the answer options

Correct option is D.

Find two numbers whose product is 80 and whose sum is 18

Amanda [17]

Let X & Y be the two integers

X+Y=18 Y = 18-X

XY = 80

We can substitute 18-X for Y in the equation XY = 80

X(18-X) = 80

Distributing

18X - X2 = 80

Subtract 80 from both sides so that the equation is equal to 0

-X2 + 18X - 80 = 0

Multiply (or divide by -1 so that the leading coefficient is positive, not negative)

X2 - 18X + 80 = 0

We can factor this quadratic

(X-10)(X-8) = 0

Setting each factor equal to 0 we can solve for X.

X-10 = 0 X-8 = 0

X = 10 X = 8

The two integers are 8 and 10.Answer:

The line through (6,-6) with slope 1/2 in point-slope form ?

aleksandrvk [35]

Answer: $y + 6 = \frac{1}{2}(x - 6)$

Step-by-step explanation:

Point-slope formula: $y - y1 = m(x - x1)$

Plug in the numbers: $y - -6 = \frac{1}{2}(x-6)$

Clear the double negatives: $y + 6 = \frac{1}{2}(x - 6)$
