Standard form [tex]1.25x-y=25[/tex]
The total amount of money is $25.
Cost of one donut is $1.25
Let y be the amount of money left
x be the number of donuts bought.
So, the amount of money left after buying x donuts is
[tex]y=25-1.25x\\\Rightarrow y=-1.25x+25[/tex]
The standard form is [tex]1.25x-y=25[/tex]

A collection of 40 dimes and nickels
is worth $2.90. How many nickels are
there? (Hint: In your equation, use
290¢ instead of $2.90.)
9514 1404 393
Answer:
22 nickels18 dimesStep-by-step explanation:
Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...
5(40 -d) +10(d) = 290
200 +5d = 290
5d = 90
d = 18
40 -d = 22
There are 22 nickels (and 18 dimes).

Additional comment
If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

Answer with Step-by-step explanation:
7x+x=90 [Being complementary angles]
8x=90
x=90/8
x=11.25
x-38+x=180 [Being supplementary angles]
2x=218
x=109
Solve for x !!!!!!!!
Answer:
x = 9
Step-by-step explanation:
to find the value of x
11x - 11 = 110 (alternate exterior angles are equal)
Substitute
11x = 110 -11
11x = 99
x = 99 ÷ 11
x = 9
Answer:
x=11
Step-by-step explanation:
Because 110= 11x-11, you can use this equation to solve.
First, add 11 to both sides:
121=11x
Then divide by 11:
11=x ------> x=11

How do you solve these two problems please explain step by step
Answer:
1) [tex]x=15, y=41[/tex]
2) [tex]x=6, y=24[/tex]
Step-by-step explanation:
1)
The two triangles are similar by AA similarity.
That means [tex]5x-5=4x+10[/tex].
We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].
We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].
We know that the [tex](5x-5)+(6y-4)=180[/tex] because they both lie on a straight line.
We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].
We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].
We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].
So, [tex]\boxed{x=15, y=41}[/tex] and we're done!
2)
Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].
We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].
We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].
We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].
We combine like terms on the left side to get [tex]25x+30=180[/tex].
We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].
We divide both sides of the equation to get [tex]x=6[/tex].
So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

Answer:
140+x+x = 180°(co-interior angle)
140+2x=180°
2x=180°-140°
2x = 40°
x = 40°/2
x = 20°
check:
140+20+20 = 180
180=180

The Hulk just flew into the Boston airport to visit some family, but due to car problems, they are
unable to pick him up. He only has $20 on him. He needs to call a cab that costs $1.75 initially and
$.65 per mile. How far will he be able to go? If his family lives 25 miles away, will the cab be able to
get him to his family?
Answer:
Yes, he will be able to afford 25 miles
Step-by-step explanation:
20.00 - 1.75 = 18.25
He will have $18.25 after the initial payment.
18.25 / 0.65 = 28~
He will be able to go 28 miles with the 18 dollars he has left.
