Same signs add for example -3 + (-4)                                                                                 Different Signs subtract for example 2 + (7)

It really depends on the sign in front of the numbers for that given example though -68-1 +(-6) you would have to add the -68 and -1 since they are both negative and then you would have to add it again to the -6 since they also have the same sign. Therefore the answer would be -75

Thomas got a flat tire and had to walk 1/4 mile to the nearest gas station. How many feet did Thomas walk?
dusya [7]

Answer:

1320\ \text{feet}

Step-by-step explanation:

The distance Thomas walked to the nearest gas station is \dfrac{1}{4}\ \text{mile}.

The conversion factor for miles to feet is

1\ \text{mile}=5280\ \text{feet}

So

\dfrac{1}{4}\ \text{mile}=\dfrac{1}{4}\times 5280

=1320\ \text{feet}

Hence, Thomas had to walk 1320\ \text{feet} to get to the nearest gas station.

32. Solve for h. bh-u+g=w
ad-work [718]

Answer:

h = \frac{w+u-g}{b}

Step-by-step explanation:

bh-u+g=w                       original

bh= w+u-g                      move everything that does not have an h to other side

h = \frac{w+u-g}{b}                        divide off b

The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?
xeze [42]

Answer:

222 boys

Step-by-step explanation:

Let x = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.

\frac{5}{6+5}x = 185 (number of girls in ninth grade)

\frac{5}{11}x = 185

x=407

To find for the number of boys, we can use substitution:

\frac{6}{6+5}x = \frac{6}{11}(407)

=222

∴ There are 222 boys in the class.

Hope this helps :)

Find the zero of the function by rewriting the function in intercept form
Marat540 [252]
Given a quadratic function
y = 4x² - 19x - 5
or i will write it as
4x² - 19x - 5 = y

Zero of the function is when y have the value of zero.
So the quadratic equation will be
4x² - 19x - 5 = y
4x² - 19x - 5 = 0

Now make the equation to intercept form by factorization
4x² - 19x - 5 = 0
(4x + 1)(x - 5) = 0   (this is intercept form)

Solution 1
4x + 1 = 0
4x = -1
x = -1/4

Solution 2
x - 5 = 0
x = 5

SUMMARY
-1/4 and 5 are zero function of f(x) = 4x² - 19x - 5
