X+3 and y=5
Let’s start with finding X
5x+3y=30
5x+3(5x-10)=30
20x-30=30(simplified)
20x-30+30=30+30(+30 to each side)
20x=60(divide by 20)
20x/20 60/20
X=3

Now to Y
Y=5x-10
Y=(5)(3)-10
Y=5 (simplified)

If triangle abc is similar to triangle mno how do I solve for value of missing side
Doss [256]

Answer:

=2.4 cm

Step-by-step explanation:

In similar plane figures, the ratio of corresponding sides is a constant.

This constant is the linear scale factor.

In the provided example, 1.2cm corresponds to 0.96 while 3.0 corresponds to x

Thus, 1.2 cm/0.96 cm=3.0 cm/x

x=(3.0 cm×0.96 cm)/1.2 cm

=2.4 cm.

P/-8 + 9 &gt; 13 <br> pls explain i don't get it
KonstantinChe [14]

Answer:

p < -32

Step-by-step explanation:

<em>Given:</em> p/-8 + 9 > 13

<em>Rewrite:</em> \frac{p}{-8} + 9 > 13

<em>Subtract 9 from both sides:</em> \frac{p}{-8}  > 4

<em>Move the negative (it is a fraction): </em>\frac{-p}{8} > 4

<em>Multiply both sides by 8:</em> -p > 32

<em>Times by -1 (-p -> -1p): </em>p > -32

<em>Flip the sign (multiplied by a negative): </em>p < -32

Hope this helps, have a nice day :D

12feet<br> 12 feet<br> HELP ME PLS SNJSNAKSKW
Flauer [41]

Answer:

20 feet.

Step-by-step explanation:

Pythagoreans theorem states that a^2 + b^2 = c^2

a = 12, squared = 144

b = 16, squared = 256

144 + 256 = 400

√400 = 20

20 feet is the answer.

Hope this helps.

How Do I solve this system of equations?<br><br> 5x+4y=-14<br> 3x+6y=6
Makovka662 [10]
3x = -6y + 6 becomes x = -2y + 2 and then you substitute in 5( -2y + 2) + 4y = -14

-10y + 10 + 4y = -14
-6y = -24
6y = 24
y = 4

And then you put y in x = -2(4) + 2 to find x
X = -8 + 2 = -6
x = -6


Then you try in both
5(-6) + 4(4) = - 14 -> -30 + 16 is -14 ✔️
3(-6) + 6(4) = 6 -> -18 + 24 is 6 ✔️
