Answer:
Step-by-step explanation:
q+n=25
n=25-q
25q+5n=505, using n=25-q in this equation gives you
25q+5(25-q)=505
25q+125-5q=505
20q+125=505
20q=380
q=19
So 19 of the coins are quarters.
Answer:
John has 19 quarters out of 25 coins.

Help plz!
Answer: a=4/3
Step-by-step explanation:
Answer:
a = 4/3
Step-by-step explanation:
Hope this will help
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1/3+a-(5/4*a)=0
5
Simplify —
4
1 5
( — + a ) - ( — • a ) = 0
3 4
1
Simplify —
3
Solve : -3a+4 = 0
Subtract 4 from both sides of the equation :
-3a = -4
Multiply both sides of the equation by (-1) : 3a = 4
Divide both sides of the equation by 3:
a = 4/3 = 1.333

Answer:
5) First you have to find x, then use it with supplementary angles theorem.
6) STQ = 150˚
Step-by-step explanation:
To find x, add (2x+8), (71-x), and 90˚ together to add up to 180˚ (those three angles are supplementary):
(2x+8) + (71-x) + 90 = 180˚
x + 169 = 180
Then solve for x:
x = 11
You can check if x is right by inputing it back into the two equations and see if all three of the angle measures together equal 180˚.
Now, you only need m∠MTS (2x+8) to find m∠STQ...
m∠MTS + m∠STQ = 180˚ because they are supplementary angles.
Input the found x to find m∠MTS:
(2(11)+8) = 30
Subtract 30 from 180 to find m∠STQ:
180 - 30 = 150
m∠STQ = 150˚
Hope this helped :)

step 2. 3t^2 +4t - 6: t is the variable, 3 and 4 are the coefficients, 2 is the degree, -6 is the constant.
step 3. 2 - h: h is the variable, -1 is the coefficient, 1 is the degree (highest variable exponent), the constant is 2.
step 4. -7a^2: a is the variable, -7 is the coefficient (before the variable), 2 is the degree, the constant is 0.
Please help! I need an explanation also because I am currently having trouble
Answer:
E = 80 degrees
Step-by-step explanation:
7x + 3 + x + 15 + 74degrees = 180
8x + 92 = 180
8x = 180 - 92
8x = 88
x=11
m<E = 7x + 3
7(11) + 3
77 + 3
= 80

Answer:
6 bowls of ramen
Step-by-step explanation:
because $1.50 * 4 is 6
49.50 - 6 = 43.50
43.50/7.25 = 6
Answer:
a)2(1.50)+7.25x=47.50
b) about 6 bowls.
Step-by-step explanation:
Right off the bat, we know that each drink is $1.50. So buying two would be $3 so far. Subtract $3 from $49.50. Getting $47.50. Now we know the drinks so we must divide 47.50 by 7.25, equalling 6.5 and so on. To round it we can say 6 bowls.

Carrah has these cans of soup in her kitchen:
2 cans of tomato soup
3 cans of chicken soup
2 cans of cheese soup
2 cans of potato soup
1 can of beef soup
Carrah will randomly choose one can of soup. Then she will put it back and randomly choose another can of soup. What is the probability
that she will choose a can of tomato soup and then a can of cheese soup?
2/10 (or 1/5 ) Times 2/10 (or 1/5).
This will equal a 1 out of 25 chance.
You take the number of items you are looking for ( for example, 2 Tomato Cans) Divided by the total items you have (All 10 cans that are a possibility). Then you take your probabilities, and multiply them.
