In the given figure, find ∠PQS, if∠PQR = 5x + 25 and∠SQR = 2x + 10.
kramer

Answer:

∠PQS= 3(x +5)

Step-by-step explanation:

∠PQR = 5x + 25

∠SQR+∠PQS= 5x+25

∠PQS = ∠PQR-∠SQR

∠PQS= (5x + 25 )-(2x + 10)

∠PQS = 5x+25 -2x-10

∠PQS= 3x +15

∠PQS= 3(x +5)

A basket contains 3/8 as many oranges as apples and three over four as many oranges as pairs what is the ratio of the number of
Gennadij [26K]
# of apples

3/8(a)=# of oranges

p=# of pears

3/4(p)=# of oranges

(3/8)a=(3/4)p

(3/8)/(3/4)=p/a

(3/8)(6/8)=p/a

3/6=p/a

1/2=p/a

the ratios of pears to apples is 1 to 2

for every 1 pear there are 2 apples

if there are 4 pears there are 8 apples

there are 8 apples

(3/8)(8)=3 oranges

there are 4 pears

(3/4)(4)=3 oranges again

8 apples, 3 oranges, 4 pears

15 pieces of fruit and 3 are oranges

ratio is 3/15=1/5

22<br> Solve for x.<br> 3x - 5 = 10<br> x equals.....<br> help
kramer

Answer:

x = 5

Step-by-step explanation:

3x - 5 = 10

We want to isolate the x.

3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\;         +5

3x = 15

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

\frac{3x}{3} \;=\;\frac{15}{3}

x = 5
