Sweets are sold loose or pre packed in 120 G bags. The 120 G bags are 1.49 pounds each By calculating the price per gram determine which is better value show ur working out
Answers
Complete question :
Sweets are sold loose, or pre-packed in 120g bags.The 120g bags are £1.49 each.The loose sweets are £0.89 for 100g.
By calculating the price per gram, determine which is better value.
Answer:
100 g bag
Step-by-step explanation:
For the 120g bag:
Price per gram :
Price / Numbe of gram
1.49 / 120 = 0.0124 gram per bag
For the 100 g bag :
0.89 / 100
= $0.0089per gram
Since $0.0089 is < $0.0124
Then the 100g bag is of better value

Delia went to the market to buy 4 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 bill and received $3.67 as change. She paid $1.29 in taxes for the fruit. What was the cost for one pound of sliced fruit before taxes?
Answers
Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
Answer:
$4.74 per pound
Step-by-step explanation:
((20 + 5) – 3.67) / 4.5 = (25 – 3.67) / 4.5 =
(21.33) / 4.5 = 4.74

Answers
Answer: h(5)=-44
Step-by-step explanation:
Given
h(t)=-10x+6
h(?)=-44
Substitute the [-44] value to the first equation
-44=-10x+6
Subtract 6 on both sides
-44-6=-10x+6-6
-50=-10x
Divide -10 on both sides
-50/-10=-10x/-10
x=5

Hi there!
For this problem, pretty much add all of them and then subtract with 22 to find how much Jen ran on Friday.
Monday+Tuesday+Wednesday+Thursday:
Simplify all terms and find all common denominators:
Common denominator: 8
[tex]4 \frac{3}{4} = 4 \frac{6}{8}[/tex]
[tex]5 \frac{1}{8} = 5 \frac{1}{8}[/tex]
[tex]6 \frac{1}{4} = 6 \frac{2}{8}[/tex]
Combine all terms:
[tex]4 \frac{6}{8} + 5 \frac{1}{8} + 6 \frac{2}{8} = 15 \frac{9}{8}[/tex]
Simplify 15 9/8 or else can’t subtract with 22.
[tex]9/8 = 1 \frac{1}{8}[/tex]
[tex]15 + 1 \frac{1}{8} = 16 \frac{1}{8}[/tex]
Turn 22 into 21 8/8...
Subtract: 21 8/8 with 16 1/8
[tex]21 \frac{1}{8} - 16 \frac{1}{8} = 5 \frac{7}{8}[/tex]
This means that 5 7/8 is how much mile Jen must run on Friday to reach her goal.

for y
y+1=3y-11
-1 from both sides
y=3y-12
-3y from both sides
-2y=-12
y=6
Answer:
x = 1 and y = 6
Step-by-step explanation:
so the opposite sides are equal to each other, therefore
4x + 7 = 12x - 1
and y + 1 = 3y - 11
so for the xs
start by adding 1 to each side
4x + 8 = 12x
subtract 4x from both sides
8=8x
divide by 8
x=1
for the ys
subtract one from each side
y= 3y -12
subract 3y from each side
-2y=-12
divide by -2
y=6
9 -4n+ 3n = 8n + 3 -3
im helping a friend so please make it right
Answers
Answer:
n = 1
Step-by-step explanation:
This equation is just basic alegebra. First, combine like terms to get
9 - n = 8n. (Because 3 - 3 = 0, and -4n + 3n = -n.) Now the equation is much simpiler; add n to both sides to get 9 = 9n. Divide 9 by both sides to get that n = 1.
You can check your answer by plugging 1 in for n.
9 - 4(1) + 3(1) = 8(1) + 3 - 3
9 - 4 + 3 = 8 + 3 - 3
5 + 3 = 11 - 3
8 = 8
Therefore, n is proven to equal 1.
