3/7=h/14-2/7 solve for h

Answer: h = 10

Step-by-step explanation:

$\frac{3}{7}=\frac{h}{14}-\frac{2}{7}$

Add $\frac{2}{7}$ on both sides to isolate $\frac{h}{14}$ .

$\frac{2}{7}+ \frac{3}{7}=\frac{h}{14}-\frac{2}{7}+\frac{2}{7}$

$\frac{2+3}{7}=\frac{h}{14}$

$\frac{5}{7}=\frac{h}{14}$

Multiply by 14 on both sides.

$14*\frac{5}{7}=\frac{h}{14}*14$

14 and 7 can be simplified.

14/7=2

7/7=1

$2*5=h$

$10=h$

3/7 + 2/7 = 5/7
5/7 = h/14
5/7 x 2 = 10/14
10/14 = h/14
h = 10

Find the intersection points of the linear and quadratic functions shown below f(x)=2x-5 g(x)= x2+2x-21

Mice21 [21]

Answer:

$(-4,-13)$ and $(4,3)$ the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

$f(x)=2x-5$

$g(x)=x^2+2x-21$

For a common point of these functions,

$f(x)=g(x)$

$2x-5=x^2+2x-21$

$-5=x^2-21$

$0=x^2-16$

$x^2=16$

$x=-4,4$

For $x=-4$ ,

$f(-4)=g(-4)=2(-4)-5$

$=-13$

For $x=4$ ,

$f(4)=g(4)=2(4)-5$

$=3$

Therefore, $(-4,-13)$ and $(4,3)$ the intersection points.

I JUST NEED #13 please and thnx

$\bf \cfrac{18}{32}\implies \cfrac{2\cdot 3\cdot 3}{2\cdot 2\cdot 2\cdot 2\cdot 2}\implies \cfrac{3\cdot 3}{2\cdot 2\cdot 2\cdot 2}\implies \boxed{\cfrac{9}{16}}\qquad \checkmark \\\\[-0.35em] ~\dotfill\\\\ \cfrac{27}{48}\implies \cfrac{3\cdot 3\cdot 3}{2\cdot 2\cdot 2\cdot 2\cdot 3}\implies \cfrac{3\cdot 3}{2\cdot 2\cdot 2\cdot 2}\implies \boxed{\cfrac{9}{16}}\qquad \checkmark$

What is 26/48 simplest form

Phoenix [80]

Answer:

13/14

Step-by-step explanation:

The GCF between 26 and 48 is 2. So divide 26/2=12 and 48/2=13 13/14. And after that you can not simplify anymore so 13/14 is 26/48 in it's simplest form.

Hope it helps!

It is given that R=2q-5 and Q=3p+2. Find the numerical value of R when p=3

saveliy_v [14]

Answer:

R = 17

Step-by-step explanation:

R = 2q - 5

Q = 3p + 2

Find the numerical value of R when p = 3

R = 2q - 5

R = 2(3p + 2) - 5

R = 6p + 4 - 5

R = 6p - 1

When p = 3

R = 6(3) - 1

R = 18 - 1

R = 17
