Answer:
£6.05
Step-by-step explanation:
Multiply the number of coffees by the cost of coffee:
5 × 65p
325p
Multiply the number of teas by the cost of tea:
2 × £1.40
£2.80
Add the two answers together:
325p + £2.80
Convert p to £
£3.25 + £2.80
£6.05
Answer:
96-28 68
Step-by-step explanation:
Answer:
<u>6b - 4a + 22 units</u>
Step-by-step explanation:
Perimeter = 2(length + width)
= 2(3b - 4a + 5 + 6 + 2a)
= 2(3b - 2a + 11)
= <u>6b - 4a + 22 units</u>
<u>Answer:</u>
The measure of the supplement of an angle is 20° More than three times the measure of the original angle. The angles are 40 degrees and 140 degrees.
<u>Solution:</u>
Given, The measure of the supplement of an angle is 20° More than three times the measure of the original angle.
We have to Find the measures of the angles.
Let the original angle be n degrees.
We know that, sum of supplementary angles is 180, then, supplementary angle of n will be 180 – n.
Now according to the given information, 180 – n = 20 + 3 x n
180 – n = 20 + 3n
3n + n = 180 – 20
4n = 160
n = 40
Then, supplementary angle is 180 – 40 = 140 degrees.
Hence, the measures of two supplementary angles are 40 degrees and 140 degrees.
