4 0

Step 1: Seperate the mixed numbers from their fractions.
$- 5 - \frac{5}{7} + 8 - 3 - \frac{2}{7}$
Step 2: Add -5 and -3. The sum of that is -8, thus we have an additive inverse. 8 and -8 cancel out, becoming a 0.
$- 8 - \frac{5}{7} + 8 - \frac{2}{7} = - \frac{5}{7} - \frac{2}{7}$
$\frac{ - 5 - 2}{7} = \frac{ - 7}{7} = - 1$
Therefore, the answer is -1

Seven tenths of a number plus fourteen is less than forty-nine

zloy xaker [14]

I'm going to assume you need this inequality solved.

First, write it as numbers, not words.

7/10n + 14 < 49

where "n" is the unknown number.

Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.

7/10 = 0.7

Now, solve it like you would any other equation.

0.7n + 14 < 49

0.7n +14 - 14 < 49 - 14

0.7n < 35

0.7n ÷ 0.7 < 35 ÷ 0.7

n < 50

The answer is n < 50

What is the measure of the exterior angle of a triangle with all 60 degree angles?

katovenus [111]

I guess you are asking the measurement of the external angle of 60. If so it will be 120 or the supplement of 60 is 120

Answer:

$\large\boxed{x=\dfrac{17}{10}=1.7}$

Step-by-step explanation:

$8=2^3\\\\\dfrac{1}{16}=\dfrac{1}{2^4}=2^{-4}\qquad\text{used}\ a^{-n}=\dfrac{1}{a^n}\\\\8^{2x-3}=\left(\dfrac{1}{16}\right)^{x-2}\\\\(2^3)^{2x-3}=(2^{-4})^{x-2}\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{3(2x-3)}=2^{-4(x-2)}\iff3(2x-3)=-4(x-2)\\\\\text{use the distributive property}\ a(b+c)=ab+ac\\\\(3)(2x)+(3)(-3)=(-4)(x)+(-4)(-2)\\\\6x-9=-4x+8\qquad\text{add 9 to both sides}\\\\6x=-4x+17\qquad\text{add 4x to both sides}\\\\10x=17\qquad\text{divide both sides by 10}\\\\x=1.7$

Soup a recipe that yields 12 cups of soup calls for 28 ounces of beef broth. How many ounces of beef broth do you need to make 1

Firlakuza [10]

One method you can use to solve this problem is by setting up a proportion.

12 cups/28 oz = 18 cups/? oz

You'll want to cross multiply 28 by 18, which equals 504. Then divide 504 by 12 and you'll get the answer 42 ounces of beef broth.
