Answer:

The shorter leg of the right triangle is 5\ cm

The other leg of the right triangle is 12\ cm

Step-by-step explanation:

Let

x-----> the shorter leg of a right triangle

y----> the larger leg of a right triangle

we know that

Applying the Pythagoras Theorem

13^{2}=x^{2} +y^{2} ----> equation A

x=y-7 ----> equation B

substitute equation B in equation A and solve for y

13^{2}=(y-7)^{2} +y^{2}\\169=y^{2} -14y+49+y^{2} \\2y^{2}-14y-120=0

using a graphing tool----> solve the quadratic equation

The solution is y=12\ cm

see the attached figure

Find the value of x

x=12-7=5\ cm

therefore

The shorter leg of the right triangle is 5\ cm

The other leg of the right triangle is 12\ cm

nordsb [41]

Answer:

j = 5

Step-by-step explanation:

16j + -6j + -12j = -10

Combine like terms

10j -12j = -10

-2j = -10

Divide by -2

-2j/-2 = -10/-2

j = 5

During a blizzard it snowed 5 and 8/10in after a week the sun had melted 3 and 1/2 inches of snow how many inches of snow is lef
WITCHER [35]

2\frac{3}{10} inches of snow is left

<em><u>Solution:</u></em>

Given that,

From given,

Original\ amount\ of\ snow = 5\frac{8}{10}\ inches = \frac{10 \times 5 + 8}{10} = \frac{58}{10}\ inches

Sun\ melted = 3\frac{1}{2}\ inches = \frac{2 \times 3 + 1}{2} = \frac{7}{2}\ inches

<em><u>how many inches of snow is left</u></em>

Snow left = original amount of snow - sun melted

Snow\ left = \frac{58}{10} - \frac{7}{2}\\\\Snow\ left = \frac{58}{10} - \frac{7 \times 5}{2 \times 5}\\\\Snow\ left = \frac{58}{10} - \frac{35}{10}\\\\Snow\ left = \frac{58 - 35}{10}\\\\Snow\ left = \frac{23}{10}\\\\\In\ mixed\ fractions\\\\Snow\ left = 2\frac{3}{10}

Thus 2\frac{3}{10} inches of snow is left
