For this use proportions.
$\frac{5}{2} = \frac{35}{x}$
Cross multiply

Help on 9 & 10 please!

Mandarinka [93]

Step-by-step explanation:

9. x and z are equal. y+z=90

148-x=180 x+148 are supplementary

-148 -148 Subtract 148 from both sides to isolate x

x=32 degrees

z=32 degrees b/c x and z are equal

y+z=90 y and z are complementary

y+(32)=90 Substitute 32 in for z

-32 -32

y =58 degrees

10. (4x-25)=(2x+7) B/c of the bisection, the two angles are equal.

4x-25 =2x+7 Remove parenthesis

-2x -2x Subtract 2x from both sides

2x-25 = +7

+25 +25 Add 25 to both sides to isolate x

2x = 32

/2 /2 Divide both sides by 2 to isolate x

x = 16

(4(16)-25)+(2(16)+7)=78 degrees Substitute 16 into the equation, this time adding the values instead of setting them equal to get the angle measure requested.

11. (6x-47)+(x+4)=90 Angles that are complementary add up to 90 degrees

7x-43 =90 Add like terms

+43 +43 Add 43 to both sides to isolate x

7x =133

/7 /7 Divide both sides by 7 to isolate x

x =19

((19)+4)=23 degrees Substitute x into the angle measure requested

12. 180=2x-9+x Use the words to help you determine what each value is.

180=3x-9 Add like terms

+9 +9 Add 9 to both sides to isolate x

189=3x

/3 /3 Divide both sides by 3 to isolate x

63=x

2(63)-9=177 degrees Substitute 63 into x to find the requested angle measure.

martin pidio 1/8 de kg de clavos de 1/2 pulgada si la bascula es digital y pesa en kilogramos ¿cuantos tienes q marcar en este c

love history [14]

Martin will have to mark 0.125 on the

Let the original weight of the scale be 1kg. Hence we can say the original mark for 1kg weight is 1 that is:

1kg = 1 ................ 1

Since we are to calculate where to mark for a 1/8 kg weight, we can write;

1/8 kg = x ..................2

Divide both expressions

$\frac{1}{1/8}= \frac{1}{x}\\\\Cross \ multiply\\8= \frac{1}{x} \\x = \frac{1}{8}$

This means Martin will have to mark 0.125 on the scale.

Find the values of X and Y in an isosceles triangle where one angle is 47°

vladimir1956 [14]

Answer:

X and Y = 66.5°.

Step-by-step explanation:

I am assuming that X and Y are the base angles, which are equal in an isosceles triangle.

X = Y = (180 - 47) / 2

= 66.5°.
