Answer:
£2.10
Step-by-step explanation:
1.80 divided by .12 = .15
.15 times 7 = 1.05
1.05 divided by 3 = .35
.35 times 5 = 2.10
The cost of 5 pens will be £1.75
Since 12 pencils cost £1.80, the price of a pencil will be gotten by dividing £1.80 by 12. This will be:
= £1.80 / 12
= £0.15
A pencil costs £0.15
Since the ratio of the cost of a pen to the cost of a pencil is 7: 3, therefore, the cost of a pen will be:
= 7/3 × £0.15
= £0.35.
The cost of a pen is £0.35, therefore, the cost of 5 pens will be:
= £0.35 × 5
= £1.75
In conclusion, the cost of 5 pen is £1.75.

A. 26 and 10
B. 18 and 8
C. 21 and 15
D. 14 and 10
Answer:
Step-by-step explanation:
a/b=7/5
a=7b/5
a+b=36, using 7b/5 for a we have
7b/5+b=36
7b/5+5b/5=36
12b/5=36
12b=180
b=15, and since a=7b/5
a=7(15)/5
a=21
So the numbers are 21 and 15

Answer:
x = 1 and y = -2
Step-by-step explanation:
Given that,
2x-3y = 8 ..(1)
4x+3y = -2 ..(2)
Add equation (1) and (2),
2x-3y+4x+3y = 8+(-2)
6x = 6
x = 1
Put the value of x in equation (1).
2-3y = 8
2-8 = 3y
-6 = 3y
y = -2
Hence, the value of x is 1 and that of y is -2.

The recipe calls for 2 2/4 but jams only have 1/4 how many cups do jams need to measure out 2 2/4 cups of raisins
Answer:
brainliest
Step-by-step explanation:
she needs altogether 2 2/4.
that is 2 wholes and 2/4 fraction.
if we consider using 1/4 cup, 1 whole is made of four quarter cups.
Therefore 2 wholes require eight quarter cups. then theres a remaining fraction of 2/4 which is equivalent to two quarter cups.
1/4 + 1/4 = 2/4. therefore altogether 8 + 2 = 10 of the 1/4 cups are required for the recipe.
10 of 1/4 cups are needed

Holly missed 7 of 183 school days this year. Approximately what percent of school days was Holly in attendance? OA. 26% B. 96% OC. 74% Reset Submit 7 of 10 Answered Session Tuner: 30-32 Session Score:
Answer:
B: 96%
Step-by-step explanation:
Since 7 out of 100 is 7% (7÷100=0.07)
then 7÷183=0.038 or 0.04. So 4% of the days she was absent. 100%-4% is 96% so holly was in attendance for 96% of the days.

John will have company when:
He rides with his friends(0.11 probability).
His parents take him(0.53 probability).
What is the probability that John will have company on the way to school?
0.11 + 0.53 = 0.64
