Answer:

Both angles are 51°

Step-by-step explanation:

By the Vertical Angles Theorem, both angles are congruent.

Step 1: Set up equation

68 - x = 3x

Step 2: Solve for <em>x</em>

68 = 4x

x = 17

Step 3: Find angles

68 - 17 = 51°

Whats the answer for 8p+21-p=7(p+3) show your work

mihalych1998 [28]

The answer is IMS,Infinite Many Solutions, because you have to do 7 (P + 3), which gives you 7p + 21. The on the other side you have to subtract 8p - p and that is 7p. So the equation would look like 7p + 21 = 7p + 21. IMS

At Quinn’s vacation wear, 1/2 of the garments

marta [7]

<h3>Answer: 5/6</h3>

Explanation:

We're asked to add the fractions 1/2 and 1/3

We can't do so right away because the denominators (2 and 3) are different. But notice how

1/2 = 3/6
1/3 = 2/6

So we can say:

1/2 + 1/3 = 3/6 + 2/6 = (3+2)/6 = 5/6

Solve this step by step please

masha68 [24]

First, put the whole fractions to mixed fractions.

First Fraction

4*3+1= 13

Always keep the denominator the same when putting whole to mixed fractions.

13/4

Second Fraction

10*1+1=11

11/10

13/4+11/10

Now, we need both denominators the same number.

13/4*5/5 =65/20

11/10*2/2=22/20

Now we have the denominators the same. We can proceed to add.

65/20+22/20= 87/20

That is the answer for mixed fraction. There is another one for WHOLE fraction.

87/20 =

$4 \times \frac{7}{20}$

"4" 7/20

Jayden has $2.95 worth of dimes and quarters. He has 2 more quarters than dimes. Determine the number of dimes and the number of

saveliy_v [14]

There are 7 dimes and 9 quarters Jayden has.

Step-by-step explanation:

Given,

Worth of dimes and quarters = $2.95 = 2.95*100 = 295 cents

One dime = 10 cents

One quarter = 25 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement;

10x+25y=295 Eqn 1

y = x+2 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$10x+25(x+2)=295\\10x+25x+50=295\\35x=295-50\\35x=245$

Dividing both sides by 35

$\frac{35x}{35}=\frac{245}{35}\\x=7$

Putting x=7 in Eqn 2

$y=7+2\\y=9$

There are 7 dimes and 9 quarters Jayden has.
