A recipe calls for their ratio of sugar to flower to be 10.3. If you use 70 ounces of sugar how many ounces of flour would you n

bulgar [2K]

This means that for every 10 of whatever measurement of sugar there will be 3 of that measurement of flour

70 oz of sugar / 10 = 7

3 (ratio of flour) times 7 = 21

5/7−(−1/7) please answer fast I need iittt

Taya2010 [7]

Answer: $\frac{6}{7}$

Step-by-step explanation:

$\frac{5}{7}-\left(-\frac{1}{7}\right)$

Once you take off the parenthesis, your sign should change from negative to positive.

$\frac{5}{7}-\left(-\frac{1}{7}\right)=\frac{5}{7}+\frac{1}{7}\\\\\frac{5}{7}+\frac{1}{7}$

The fractions now both have the same denominator. Thus, we can add the numerators.

$\frac{5+1}{7}\\\\5+1\\\\6=\frac{6}{7}$

Therefore, $\frac{5}{7}-\left(-\frac{1}{7}\right)=\frac{6}{7}$

PLEASE HELP MEE I CAN'T SOLVE THIS BY MYSELF!

UNO [17]

Answer:

x = 22

Step-by-step explanation:

The figure is attached below.

Its given that SV is parallel to RU. We have to find the value of x.

Observe that, if we join point V to U, we will obtain a parallelogram RSVU. One of the properties of a parallelogram is that the sum of its two adjacent angles is always 180 degrees.

So, the two adjacent angles would be: ∠S and ∠R

From the figure:

∠S = 5x + 4

∠R = 44 + x

Since,

∠S + ∠R must be 180 degrees, we can write:

∠S + ∠R = 180

5x + 4 + 44 + x = 180

6x + 48 = 180

6x = 132

x = 22

Therefore, the value of x is 22.
