Answer:
when opening the bracket remember that the value outside the bracket will be used to multiply the value inside the bracket
Same-side interior angles are supplementary, so add to 180°.
Opposite side exterior angles are equal.
Solve these by using the appropriate relation with the given expressions.
9) (x +134) +(x +64) = 180
.. 2x +198 = 180
.. x = (180 -198)/2 = -9
The angles are 125° (top) and 55° (bottom).
Answer:
21 ounces of flour
Step-by-step explanation:
10/3 = 70/x
isolate the so that it is on the top, so multiply by x on the right and on the left
this gives you:
x*10/3=70
try to isolate x and multiply by 3 to get rid of the denominator
x*10=70*3
x*10= 210
finally isolate x by dividing by 10 and getting rid of the 10 multiplying with it
x= 210/10
x=21
you need 21 ounces of flour if you have 70 ounces of sugar you can double check by making sure the ratio of 10/3 is equal to 70/21 and of course they both equal 3.33 repeating, therefore your answer is correct Hope that helps
I don't understand
one way you could consider 'simplifying' is to make all numbers whole and simplest form
I will put it into stardard form which is ax+by=c
make all numbers whole
2.1x-0.9y=15
multiply everybody by 10
21x-9y=150
divide everybody by 3
7x-3y=50
