Ben and Jane are both bringing cupcakes to school. Ben brings 25 cupcakes, and Jane brings 6 times as many cupcakes as Ben. Jane put an equal number of cupcakes on each of the 8 tables in her classroom out of the cupcakes she has brought. How many cupcakes could Jane put on each table out of the cupcakes she brought if each table will have the same number of cupcakes?
Answer:
Step-by-step explanation:
25 x 6 = 150. Then you do 150 divided by 8 = 18.75. (You have a remainder of 6) Jane could put 18 cupcakes on each table so each table so they all have the same amount of cupcakes.
Answer:
25 x 6 = 150 then divided by 8 = 18.75.

Spencer would like to attend the University of El Dorado, which costs $24,000 per year. He plans to save money each month for the next 4 years in order to reach his goal. His grandparents will contribute 25% for his first year's tuition. If Spencer also receives a local scholarship for $3,000, how much money will he need to save each month to cover his first year of tuition?
Answer:
well he has 9,000 so 24,000 - 9,000 = 15000 so he needs 15000 for the year, divided by 12 (each month) is 1250. So each month he needs to save 1250

Write an equation of the line that passes through each pair of points.
Make sure it’s an equation with y=mx+b
(-8,-3), (-1,-2)
please provide explanations because i’m studying and point grinding WILL BE REPORTED
Answer:
[tex]y = \frac{1}{7} x - 1 \frac{6}{7} [/tex]
Step-by-step explanation:
In y= mx +b, m is the slope and b is the y-intercept.
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
where (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate
Slope
[tex] = \frac{ - 3 - ( - 2)}{ - 8 - ( - 1)} [/tex]
[tex] = \frac{ - 3 + 2}{ - 8 + 1} [/tex]
[tex] = \frac{ - 1 }{ - 7} [/tex]
[tex] = \frac{1}{7} [/tex]
Substitute m= ⅐ into the equation:
y= ⅐x +b
To find the value of b, substitute a pair of coordinates into the equation.
When x= -1, y= -2,
-2= ⅐(-1) +b
-2= -⅐ +b
b= ⅐ -2
[tex]b = - 1 \frac{6}{7} [/tex]
Thus the equation of the line is [tex]y = \frac{1}{7} x - 1 \frac{6}{7} [/tex].

10 points pls make an explination.....
Answer:
26
Step-by-step explanation:
Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.
Time getting dressed = ¹/₃x
Eating breakfast = 10 mins
Making bed = 5 mins
¹/₃x + 10 + 5 = 35 ½
¹/₃x + 15 = 35 ½
¹/₃x = 35 ½ - 15
¹/₃x = 20 ½
x = 20 ½ / ¹/₃
= 61.5 minutes
Total morning routine is is 61.5 mins
Time taken to drive to work is;
= 61.5 - 35 ½
= 26 minutes

Write a linear equation in slope-intercept form.
y=mx+b answer
step by step y=mx+b
Answer: y = 4x
Step-by-step explanation:
The slope-intercept form is written as y = mx + b, m is the slope, and b is the y-intercept, the y value when x is 0.
When x is 0, then y is 0. In this case, the y-intercept is 0.
Solve for slope, choose two-point, (0,0) and (1,4).
Slope = (y2 - y1)/(x2 - x1)
= (4 - 0)/(1 - 0)
= 4/1
=4.
Plug the slope and y-intercept in, where m is 4 and b is 0.
we get y = 4x + 0 = 4x

find the 64th term in the number sequence
4,9,14,19
Answer:
The 64th term in the number sequence 4, 9, 14, 19... is 319
Step-by-step explanation:
a₁ = 4, a₂ = 9, a₃ = 14 and n = 64
Now, Common Difference (d)
d = a₂ - a₁ = 9 - 4 = 5
d = a₃ - a₂ = 14 - 9 = 5
Here, Common Difference is same everywhere,
Now,
aₙ = a + (n - 1)d
a₆₄ = 4 + (64 - 1) × 5
a₆₄ = 4 + (63) × 5
a₆₄ = 4 + 315
a₆₄ = 319
Thus, The 64th term in the number sequence 4, 9, 14, 19... is 319

The graph of the inequality is in the picture and the solution set to the inequality is (-∞, 26/3).
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The linear equality is:
(1/2)x - 3 < -1 3/8
x/2 - 3 < -11/8
x/ 2 < -11/8 + 3
x/2 < 13/3
x < 26/3
Thus, the graph of the inequality is in the picture and the solution set to the inequality is (-∞, 26/3).
