Mathematics

Answer:

See below.

Step-by-step explanation:

4x + 3y < 12

-x + 3y < -3

First find where the 2 lines intersect

4x + 3y = 12

-x + 3y = -3

Subtract :

5x = 15

x = 3

and y = -3 + 3 / 3 = 0

So they intersect at the point (3,0).

Therefore there are many ordered pairs below these 2 lines that satisfy this inequality.

Trevor measured the town library and made a scale drawing. In real life, the parking lot is 75 meters long. It is 135 centimeter

jasenka [17]

Answer: $9\ cm\equiv 5\ m$

Step-by-step explanation:

Given

The actual length of the parking lot is 75 m

length in the drawing is 135 cm

Here, 75 m is equivalent to 135 cm

Using unitary method

$75\ m\equiv 135\ cm$

$15\ m\equiv 27\ cm$

$9\ cm\equiv \frac{15}{3}=5\ \text{m}$

Helen spent 7.75 to purchase 23 snack sized bags of chips (c) and pretzels (p). Chips cost 0.25 and pretzels cost 0.50. How much

hodyreva [135]

Answer:

15 chips and 8 pretzels

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

Total spent = $7.75

Number of snacks = 23

Chips cost = $0.25

Pretzels cost = $0.50

Let number of chips = X

So, number of pretzels = 23 - X

So, we can calculate number of snacks by using following equation

0.25X + 0.50 ( 23 - X) = $7.75

0.25X + 11.50 - 0.50X = 7.75

0.25X - 0.50X = 7.75 - 11.5

-0.25X = -3.75

X = -3.75 ÷ -0.25 = 15

Hence, Number of chips = 15

Number of Pretzels = 23 - 15 = 8

-1/2 +2=-x+7 how do you figure this out

Feliz [49]

Answer:

x = 5.5

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

$-\frac{1}{2} +2=-x+7$

$-\frac{1}{2} +2= 1.5$

$1.5=-x+7$

-7 -7

$-5.5 = -x$

Divide both sides by -1.

$5.5 = x$
