Answer:
Solution given:
y=3-4x.....[I]
y=4+½x...[2]
Equating equation 1 and 2
3-4x=4+½x
6-8x=8+x
6-8=8x+x
x=-2/9
x=-0.22
substituting value of x in equation I
y=3-4(-0.22)
y=3.89
(x,y)=(-0.22,3.89)
Yes you are right:
Equate and solve
3-4x=4+0.5x-1=4.5xx=-1/4.5x=-0.22Option B as it only has x=-0.22

Marty’s water bottle holds 4 cups of liquid. He has 24 fl oz of water to put into the bottle. Will all 24 fl oz fit in the bottle?
Answers
Answer:
yes all fl oz will fit in the bottle
Step-by-step explanation:
1 cup = 8 fl oz
4 cups = 32 fl oz
you have still space 8 fl oz
Yes, all 24 fl oz will fit in the bottle.
What are Units ?To measure and compare various things we use one term which is known as a unit. When all of the measuring units are the same, comparison is simple.
We need to convert both the capacity of the water bottle and the amount of water in fluid ounces to the same unit before we can compare them.
1 cup = 8 fluid ounces, so 4 cups = 32 fluid ounces.
Therefore, the water bottle can hold 32 fluid ounces of liquid.
Marty has 24 fluid ounces of water to put into the bottle.
Since 24 fluid ounces is less than 32 fluid ounces, all 24 fluid ounces of water will fit into the water bottle with room to spare.

Crystal has $9 to spend on lunch and an afternoon snack. If lunch costs three times as
much as the snack, which inequality best represents the situation if s represents the
money that can be spend on a snack?
A. 3s + s less than or equal to 9
B. 3s greater than or equal to 9
C.3s + s greater than or equal to 9
D.s less than or equal to
Answers
Answer:
The answer is C as money needed to spend on lunch is 3times on snacks so if we let money on snacks as s then lunch will be 3s.
Step-by-step explanation:
And the total money he has is $9 so
3s+s = 9
The inequality will be 3s + s greater than or equal to 9. The correct option is C.
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to, > ‘greater than, or < ‘less than.
It is given that Crystal has $9 to spend on lunch and an afternoon snack. If lunch costs three times as much as the snack.
The answer is C as the money needed to spend on lunch is 3 times on snacks if we let money on snacks as s then lunch will be 3s. And the total money he has is $9.
3s+s = 9
Therefore, the inequality will be 3s + s greater than or equal to 9. The correct option is C.

A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?
Answers
Answer:
3 doors needed
Step-by-step explanation:
The computation of the no of trucks doors that are needed is shown below:
= serve daily ÷ no of store orders ÷ no of store orders
= 50 ÷ 4 ÷ 4
= 3 doors needed
First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come

Find the sum of the first 10 terms of the following sequence. Round to the nearest
hundredth if necessary.
200,
-160,
128,...
Answers
Answer:
S_n = 99.18
Step-by-step explanation:
The series is;
200, -160, 128...
Now,the common ration would be gotten by dividing two consecutive terms i.e. a2/a1, a3/a2, a4/a3 e.t.c.
Now,
r = -160/200
r = -4/5
Formula for sum of geometric series is;
S_n = a1(1 - rⁿ)/(1 - r)
Where a1 is the first term and n is the number of terms in the series.
In this case;
a1 = 200
n = 10
Thus;
S_n = 200(1 - (-4/5)^(10))/(1 - (-4/5))
S_n = 99.18
