Answer:
28
Step-by-step explanation:
Let n = 21, and evaluate the expression.
Answer:
61°
Step-by-step explanation:
Since the angles make up a full circle which is 360°, deduct all the degrees with numbers from 360°
360 - 65 - 50 - 62 = 183
x + 2x = 3 x
3x = 183
x = 183 ÷ 3 = 61
There are 3 parts to the ratio so...
First we divide the total number of objects we are sharing (in this case 15 biscuits) by the number of parts in the ratio (3)
15 / 3 = 5
Then we know that each part of the ratio is worth 5 biscuits. So we times each part of the ratio by how many biscuits are in one part...
1 x 5 = 5
2 x 5 = 10
So when the biscuits are shared into the ratio 1:2, the number of biscuits in each are 5:10
Hope this helps :)
Answer:
y = 1/2x + 1
Step-by-step explanation:
The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.
The line crosses the y axis at positive 1 and that is the y-intercept.
