10=ax-3b solve for x

2 answers:

8 0

10 = ax - 3b

First, add 3b to both sides. / Your problem should look like: 10 + 3b = ax.
Second, divide both sides by a. / Your problem should look like: $\frac{10 + 3b}{a}$ = x.
Third, switch sides. / Your problem should look like: x = $\frac{10 + 3b}{a}$ which is your answer.

10 = ax - 3b
10 + 3b = ax

x = (10+3b)/a

Factor this trinomial 4x^2-6x-10 If you can please try to show me how to do it.

lilavasa [31]

Answer:

$=2(2x-5)(x+1)$

Step-by-step explanation:

So we have the trinomial:

$4x^2-6x-10$

First, factor out a 2:

$=2(2x^2-3x-5)$

Now, factor within the parentheses.

To do so, we want to find two numbers. When multiplied, these two numbers must equal (a)(c) and when added, they must equal b

(a)(c) is 2(-5) or -10 and b is -3. So, we want two numbers that when multiplied together gives -10 and when added gives -3.

-5 and 2 works. Therefore:

$=2(2x^2-3x-5)$

Replace -3x with 2x and -5x:

$=2(2x^2+2x-5x-5)$

Factor out a 2x for the first two terms. And factor out a negative 5 for the remaining two:

$=2(2x(x+1)-5(x+1))$

Grouping:

$=2(2x-5)(x+1)$

And we're done!

The price of a carton of eggs at Supermarket A is $2.10. The price of a carton of eggs at Supermarket B is 40% less than the pri

igor_vitrenko [27]

Answer:

84 Percentage increase

Step-by-step explanation:

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 40% of its value.

Percentage increase = 40% × 210

New value = 210 + Percentage increase

Calculate the New Value

New value =

210 + Percentage increase =

210 + (40% × 210) =

210 + 40% × 210 =

(1 + 40%) × 210 =

(100% + 40%) × 210 =

140% × 210 =

140 ÷ 100 × 210 =

140 × 210 ÷ 100 =

29,400 ÷ 100 =

294

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 210 =

294 - 210 =

How many 10 oz servings are in a 5-quart pitcher of lemonade?<br><br>There are ? Servings

Ira Lisetskai [31]

Answer:

There are 16 servings

Step-by-step explanation:

<u>First, find how many oz are in 5 quarts. </u>

<em>Think: In one quart there are 32 ounces, in 5 quarts how many ounces would that be?</em>

5 x 32 = 160 ounces

<u>Next, divide 160 ounces by 10 servings</u>

160 / 10 = 16 servings

So there are 16 servings in a 5 quart pitcher.

Hope this helps ;)

Determine if y varies directly with x. Give the constant of variation, when appropriate. (picture below)

maxonik [38]

Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.

<h3>Variation</h3>

y = k × x

where,

k = constant of proportionality

y = -40

x = -5

y = k × x

-40 = k × -5

-40 = -5k

k = -40/-5

k = 8

when,

y = 8 and x = 2.5

y = k × x

8 = k × 2.5

8 = 2.5k

k = 8/2.5

k = 3.2

when,

y = 5 and x = 4

y = k × x

5 = k × 4

5 = 4k

k = 5/4

k = 1.25
