Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
The question is very vague, but here's what it tells me.
We know that the coordinates are (4, 25) meaning the x is 4 and the y is 25.
Since time is x and height is y, all this is saying is this:
After 4 weeks, the corn stock is 25 inches.
You can go deeper and divide 25 by 4 to find out the rate of growth. That would give you 6.25, meaning
The corn stock grows 6.25 inches every week.
Step-by-step explanation:
x = 2.5
5x
5 × 2.5
12.5
5x = <u>12.5</u>...
Answer:
Step-by-step explanation:
Given expression
To solve for 
for the given expression.
Solution:
We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.
The multiples of the denominators are:
3 = 3,6,9,<u>12</u>,15
6 = 6,<u>12</u>
4 = 4,8,<u>12</u>
The least common multiple = 12.
Multiplying each term with 12.
Using distribution.
Simplifying.
Adding 
both sides.
Adding 51 both sides.
Dividing both sides by 15.
Simplifying fractions.
∴ (Answer)
