(let x represent the blank)

3/8 + 2/3 = x + 3/8
25/24 = x + 3/8
subtract 3/8 from both sides of the equation
2/3 = x

The answer would be 2/3

Solve for w. 9w-4/4=5w-6/7+6

ELEN [110]

Answer:

$w=\frac{1}{16}$

Step-by-step explanation:

$\frac{9w-4}{4} =\frac{5w-6}{7+6}$

$9w-1=\frac{5w-6}{13}$

$9w-1+1=\frac{5w-6}{13}+1$

$9w=\frac{5w-6}{13}+1$ <u />

13 × 9w = 13 × $\frac{5w-6}{13}+1$

117w = 5w - 6 + 13

117w = 5w + 7

117w - 5w = 5w - 5w + 7

112w = 7

112w ÷ 112 = 7 ÷ 112

$w=\frac{1}{16}$

One positive number is 4 more than twice another. Their product is 198

EastWind [94]

Answer:

$\large \boxed{\sf \ \ 9 \text{ and } 22 \ \ }$

Step-by-step explanation:

Hello,

We can write that, x being the second number

(4 + 2*x) *x = 198

Let's solve this equation.

$(4+2x)x=198\\\\4x+2x^2=198 \\\\\text{*** subtract 198 from both sides ***}\\\\2x^2+4x-198 = 0\\\\\text{*** The product of the zeroes is -198/2=-99=-11*9 and their sum is -4/2=-2 ***}\\\\2x^2+4x-198=2(x-9)(x+11)=0\\\\x=9 \ \ or \ \ x=-11$

We are looking for positive number so the solution is 9.

And the first number is 4 + 2 * 9 = 4 + 18 = 22

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

Given triangle QRS = triangle TUV, find the measure of the given angles and the lengths of the given sides.

Amiraneli [1.4K]

Answer:

A. 16; 36

Step-by-step explanation:

If the triangles are equal

sides QS = side TV

3v+1 = 5v-9

subtract 3v from each side

3v+1 -3v = 5v-3v-9

1 =2v-9

add 9 to each side

1+9 = 2v-9+9

10 = 2v

divide by 2

10/2 =2v/2

5=v

QS = TV = 3v+1 = 3(5)+1 = 16

<r = <u

4n+4 = 5n-4

subtract 4n from each side

4n+4 -4n = 5n-4n -4

4 = n-4

add 4 to each side

4+4 =n-4+4

8 =n

<r = <u = 4n+4 = 4*8+4 = 36
