First calculate x.
since its an isosceles triangle, and the 2 isosceles sides r same so the base angles are the same
therefore 7x + 5 = 9x - 13
5 + 13 = 9x - 7x
2x = 18
x = 9
so when we have x = 9, just use the angle sum of triangle to calculate y.
4y + 7x9 + 5 + 9x9 -13 = 180
4y + 136 = 180
y= 11
so there u have it, x is 9 ans y is 11

The ratio of cars to trucks is 9:4. The ratio of trucks to SUV's is 12:21. There are 54 cars.
Elenna [48]

Answer:

Number of trucks = 24

Number of SUVs = 24

Step-by-step explanation:

A)

The ratio of cars to trucks is 9:4

The total ratio of cars to trucks is

9+4 = 13

Let x = sum of cars and trucks.

There are 54 cars. Therefore,

x = 54 + t trucks

Number of cars = ratio of cars/ total ratio × sum of cars and trucks. This means,

54 = 9/13 × x

9x / 13 = 54

9x = 13 × 54

9x = 702

x = 702 / 9 = 78

x = 54 + t trucks = number of trucks = 78 = 54 + t trucks

t trucks = 78 - 54 = 24

Number of trucks = 24

B)

The ratio of trucks to SUVs is 12:21

The total ratio of cars to trucks is

12 + 21 = 33

Let y = sum of trucks and SUVs

There are 24 trucks. Therefore,

x = 24 + s SUVs

Number of trucks = ratio of trucks / total ratio × sum of trucks and SUVs. This means,

24 = 12 / 33 × y

12y / 33 = 24

12y = 24 × 33

12y = 792

y = 792 / 12 = 66

y = 24 + s SUVs

66 = 24 + s SUVs

s SUVs = 66 - 24 = 42

Number of SUVs = 24

I need help to find the measures and equation pls.
siniylev [52]

Answer:

Equation: 7x + 8x = 180

x = 12

∠CBA = 84

∠CFH = 96

Step-by-step explanation:

We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.

We know that the sums of two angles on a straight line are going to be equal to 180.

∠CBA = 7x

∠CFH = 8x

To find the value of x, we must do the following:

7x + 8x = 180

15x = 180

15x/15 = 180/15

x = 12

Now we just substitute to find the angle measures:

∠CBA = 7 · 12 = 84

∠ CFH = 8 · 12 = 96

Solve this expression 8÷2*5+(6-4)
Annette [7]

Value of expression \frac{8}{2}(5) + (6-4) is 22 .

<u>Step-by-step explanation:</u>

Here we have the following expression to solve :

8÷2*5+(6-4)

⇒ (8/2)*5 + (6-4)

⇒ \frac{8}{2}(5) + (6-4)

But 8 = 4(2) , So

⇒ \frac{4(2)}{2}(5) + (6-4)

⇒ 4(5) + (6-4)

⇒ 20 + (6-4)

⇒ 20 + 2

⇒ 22

Therefore, Value of expression \frac{8}{2}(5) + (6-4) is 22 .
