Step-by-step explanation:
1 can of corn = c
1 can of green beans = b
Marissa-> 4c+8b=7
Bob-> 8c+7b=8.60
form a simultaneous equation:
4c+8b=7
8c+7b=8.60
find a common coefficient, e.g. make the number of cans of corn that Marissa has, equal to the number of cans of corn that Bob has, so you would multiply the top equation by 2, so both people have 8 cans of corn
8c+16b=14
8c+7b=8.60
now you can cancel out the cans of corn, and subtract the second equation from the first one, so you would get:
16b-7b=9b
14-8.60= 5.4
so, 9b=5.4, and b= 0.6
so 1 can of green beans would cost $0.60
Milan
putting money into a savings account. He starts with $350 in the savings account, and each week he adds $60.
Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Milan has been adding money. Write an
equation relating S to W. Then use this equation to find the total amount of money in the savings account after 17 weeks.
Answer:
Milan will have $1,370 in the account after 17 weeks.
Step-by-step explanation:
S(W) = 350 + 60W
S(17) = 350 + 60*70 = 1370
y=sxw+n
y= 350xw+60

Answer:
It is because they are fractions of the same numbers so if you devide the numerator, you will get the quotient

Which image is the translation of ΔABC given by the translation rule (x,y) → (x-2, y-2)?
A. (look at pic)
B. (look at pic)
C. (look at pic)
D. (look at pic)
Answer:
D
Step-by-step explanation:
So when you translate triangle ABC, you have to subtract 2 from each part of the coordinate, aka move it 2 to the left and 2 down.
Therefore, it would be D
Hope that helps! :D

Question 12: H. Howard Hughes, Professor Emeritus of Texas Wesleyan
College, and his wife Erin Connor Hughes attended a record 6136
theatrical shows. Write an expression for the number of shows they
attended per year if they accumulated the record over "Y" years. *
Answer:
6136 / Y
Step-by-step explanation:
Total number of theatrical shows = 6136 shows
Total shows was attended over a period of Y years
Hence, number of shows attended per year:
(Total Number of shows / period of years between which shows was attended)
= 6136 / Y

a waterslide has an angle of elevation of 20 degrees whats is the rise for a run of 2.6 m?
Answer:
Therefore, the rise will be 0.95 m
Step-by-step explanation:
As the waterslide has an angle of elevation of 20 degrees.
Ф = 20°
And we have to determine the rise for a run of 2.6 m.
All we need is to use the trigonometric ratio of tan Ф
Because
tan Ф = rise/runAs
run = 2.6 m
Ф = 20°
so
tan Ф = rise/run
tan (20) = rise/run
rise = tan (20) × 2.6
rise = 0.95 m
Therefore, the rise will be 0.95 m

what is the value of x for the equation: x/3+x=x/6-1
Answer:
I think the answer may be
X=2
Step-by-step explanation:
x÷3+x=x÷6-1
Add the common factors together to get
2x÷3=x÷6-1
subtract on the right side to get
2x÷3=x÷5
subtract 3 from both sides to get
2x=x÷2
subtract x from both sides to get
1x=2

a rectangle has an area of 651m². One of the sides is 7m in length. Work out the perimeter of the rectangle
Answer:
200
Step-by-step explanation:
So first off, let's find the other side.
651 divided by 7 = 93
93 would be the other side measurement. There are two sides that measure 93 degrees, two sides that measure 7 degrees.
93 + 93 + 7 +7 = perimeter
Once we add up like terms, 200

Nick is given $50 on a vacation. He decides to spend $5 a day. Write an equation relating to the amount of money Nick has left, y, and the number of days, x, Nick spends money
Answer:
y = -5x + 50
Step-by-step explanation:
We'll write the equation in y = mx + b form, where b is the original amount of money (50), and m is the amount of money he spends he each day(5). Since he's spending 5 dollars, that means that 5 dollars is being lost everyday, so m will be -5:
y = -5x + 50
