Sandra has some nickels, dimes, and quarters which total $2.50. She has the same
number of nickels as quarters; however, she has twice the number of dimes as nickels.
How many of each type of coin does she have?
Answer:
5 nickels
10 dimes
5 quarters
Step-by-step explanation:
n = number of nickels
d = number of dimes
q = number of quarters
q = n
d = 2n
0.05n + 0.10d + 0.25q = 2.50
substitute
0.05n + 0.10(2n) + 0.25(n) = 2.50
0.05n + 0.20d + 0.25n = 2.50
0.50n = 2.50
n = 5
d = 10
q = 5

-2(4x – 3) = 10
Can someone help me with this math problem please
Answer:
-1/2
Step-by-step explanation:
-2(4x - 3) = 10
First distribute the -2 to 4x and -3; it turns into
-8x + 6 = 10
The subtract 6 on both sides which equals
-8x = 4
Then divide -8 on both sides...
x = -4/8 or -1/2
Can someone help me?
Answer:
Step-by-step explanation:
5y-7=5d+3y
we will subtract 3y from both sides
5y-3y-7=5d
we will add 7 on both sides
2y=5d+7
we divide by 2
y=(5d+7)/2
or
y=5d/2+7/2

Starbucks opened two new locations. Location A costed $800 to open but makes $100 a month. Location B costed $1200 to open but makes $200 a month. Determine how long it will take for the locations to have made the same amount after paying off their costs and how much that amount is. *
Answer:
I think it is A that will take longer but im not 100 percent sure
Step-by-step explanation:
First write an equation:
Location A- 800+100x
Location B- 1200+200x
Then you need to plug numbers in for x
R(-9,4) and S(2,-1); Find T
Answer:
The question doesn’t state what T represents, so I will assume T is one of two points:
1. The midpoint of R and S, or
2. S is the midpoint of RT.
1. T((-9+2)/2,(4-1)/2)=T(-7/2,3/2)
2. T(x,y): S(2,-1)=((-9+x)/2,(4+y)/2); 2=(-9+x)/2, 4=-9+x, x=13; (4+y)/2=-1, 4+y=-2, y=-6. T(13,-6)
Write the phrase "the sum of a number and twenty-three less than that number" as a mathematical expression.
A) x + 23
B) x ⋅ 23
C) x – 23
D) x + (x – 23)
Answer:
D
Step-by-step explanation:
The sum of a number and twenty-three less than that number" as a mathematical expression is x + (x – 23)
I mean its the only answer with sum and "less than" because that usually means you need to subtract, I hope this helps

What is the perimeter of the shape below, given a = 5.66, b = 13.75, c = 6.76, d = 4.59
Answer:
61.52
Step-by-step explanation:
5.66+ 13.75 + 6.76 + 4.59 + 5.66+ 6.76 + 13.75 +4.59
Answer:
61.52
Step-by-step explanation:
Given the values, you can solve for the remaining sides.
a + c will equal the side on the right and b + d will equal the side at the top.
So 2(a+c) + 2(b+d) will give the perimeter.
2(5.66+6.76) + 2(13.75+4.59) = 24.84 + 36.68 = 61.52

At a garage sale, a large bin full of DVDs and CDs are being sold. All the DVDs are the same price, and all the CDs are the same price.
Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?
Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?
Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Ling bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)

Factorization of the given algebraic expression in its' simplest form is; B.–2(a + 6)
How to factorize an Algebraic Expression?To factorize an algebraic expression, it means that the highest common factors of the terms of the specific algebraic expression are determined and then we group the terms accordingly.
We are given the algebraic expression as;
6a – 4(2a + 3)
Multiplying the bracket out gives us;
6a - 4(2a) - 4(3)
= 6a - 8a - 12
= -2a - 12
Now, the highest common factor of the expression is 2 and so we have;
-2(a + 6)

.) A group of neighborhood families are planning a trip to the museum. Tickets are $25 for adults
and $10 for children. The group also has a coupon for $5 off. The expression 25a + 10c – 5
represents the total cost for a adult and c child tickets. Monica is purchasing tickets for
5 adults and 9 children.
Answer:
$210
Step-by-step explanation:
the expression is 25a+10c-5
where a=adults,c=children
and we have 5adults and 9 children
then 25a + 10c - 5 is
25(5)+10(9)-5
=125+90-5
=210
