Sam has 6x + 8 dollars saved. Teresa has saved 14x + 32 dollars. Together they have $220 saved. How much money have they each saved individually?
Answers
Step-by-step explanation:
given,
dollars saved by Sam = 6x + 8
dollars saved by Teresa = 14x + 32
total money = $220
a/q
money saved by,
sam + Teresa = $220
so,
6x + 8 + 14x + 32 = 220
20x + 40 = 220
20x = 220 - 40 = 180
x = 180/20 = 9
x = 9
now,
money saved by,
Sam = 6x + 8 = 6(9) + 8 = $62
Teresa = 14x + 32 = 14(9) + 32 = $158
therefore,
money individually saved by Sam is $62 and by Teresa $158.

Anthony is building a cube-shaped box to store some of his smaller crafting supplies. The formula for the surface area of a cube is SA=6s2, where s is the side length of the cube. If he has a total of 200 in.2 of cardboard, can Anthony build a box where s=6 in.?
No, he needs 16 in.2 more cardboard.
No, he needs 232 in.2 more cardboard.
Yes, he will have 56 in.2 of cardboard left over.
Yes, he will have 128 in.2 of cardboard left over
Answers
Answer:
No, he needs 16 inches^2 more cardboard.
Step-by-step explanation:
Take the formula and substitute values into it. 6 * 6^2
Do the exponent first to get 6 * 36, and then complete that to get 216. Since he has 200 inches of cardboard and he would need 216, that means he would need 16 more square inches to make his cube.

Fill in the next two terms in the pattern. Enter your answers in the boxes.
0.16, 0.35, 0.54,
,
Answers
Answer:
By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.
Step-by-step explanation:
Answer:
0.73 and 0.92
Step-by-step explanation:
The difference of the first 3 is 0.19 per step, so continuing that is 0.73 and then 0.92

Answers
Answer:
12 shirts
Step-by-step explanation:
First, let x = # of shirts and y = total cost in $. Then create an equation with x and y representing each company. The first company is y = 9.65x + 43 and the second company is y = 8.40x + 58. Since we need to find the # of shirts that would result in the equal total cost, we need to find x when y is equal to the other. Thus here is the setup: 9.65x + 43 = 8.40x + 58, and we would get 1.25x = 15, so x = 12.
Company 1–> 9.65x+43
Company 2–> 8.40x+58
Next you set them equal to each other
9.65x+43=8.40x+58
9.65x-8.40x=58-43
1.25x=15/1.25
x=12
When you plug 12 into both equations you’ll get that they both equal 158.8

Given that, nine cyclists were each asked the distance in miles they biked last week. The distance travelled by 9 cyclists is 16, 8, 2, 6, 8, 11, 9, 15 and 7.
We need to complete the grouped frequency distribution for the data.
What is the grouped frequency distribution?In this type, the data is arranged and separated into groups called class intervals. The frequency of data belonging to each class interval is noted in a frequency distribution table. The grouped frequency table shows the distribution of frequencies in class intervals.
Now, the frequency distribution for the given intervals is as follows:
That is, for intervals 2 to 7 the frequency is 3.
For intervals 8 to 13 the frequency is 4.
For intervals 14 to 19 the frequency is 2.

A = small box of oranges
B = large box of oranges
3A + 14B = 203
11A + 11B = 220
Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:
[tex]\frac{11A+11B}{11}[/tex] = A + B
220 will also have to be divided by 11, giving you 20
A + B = 20
You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.
11B = 143
143/11 = 13
B (large box of oranges) costs $13.
Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60
3A + 3*13 = 60
3A + 39 = 60
3A = 21
A = 7
Thus:
A small box of oranges costs $7, and a large box of oranges costs $13.

Okay, so the triangle would look something like this:

Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.
*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa
