Answer:
.25x+1.75=15 and x=53
Step-by-step explanation:
first subtract 1.75 from both sides
then divide by .25 on both sides
and you will get x=53
A)
Because the sum of angles in a triangle must equal 180° we can say:
62+α+90=180
α+152=180
α=28°
b)
Since all sides have equal length, all angles must have equal measure. (This is an equilateral triangle). And again, because the sum of the angle must be 180° we can say:
b+b+b=180
3b=180
b=60°
Answer:
An equation that expresses a relationship between two or more variables, such as Upper H equals nine tenths left parenthesis 220 minus a right parenthesis , is called Formula.
A formula is an equation that expresses a relationship between two or more variables.
The process of finding formulas to describe real-world phenomena is called mathematical modeling.
Such equations, together with the meaning assigned to the variables, are called mathematical models.
Complete question :
Jordan is mixing water and flour to make tortillas. The number of cups of water, w, needed for f cups of flour is described by the equation w = 0.75f
How many cups of water are needed to mix with 4 cups of flour?
Answer:
3
Step-by-step explanation:
Given the relation :
w = 0.75f
Where w = number of cups of water ; f = cups of flour
Cups of water needed to mix 4 cups of flour :
f = 4
w = 0.75(4)
w = 3
Hence, 3 cups of water is required to mix 4 cups of flour.
