MULTIPLE CHOICE What is LM? 3x + 5 4x + 7 LN = 33 cm

Mathematics

1 answer:

FromTheMoon [43]3 years ago

7 0

Answer:

C. 14

Step-by-step explanation:

Add LM and MN

(3x + 5) + (4x + 7)

(4x + 3x) + (5 + 7)

7x + 12

As we know the total is 33

So,

7x + 12 = 33

Subtract 12 from 33, which gives me 21

Now,

7x = 21

To make x alone, divide both sides by 7, and then we will get x = 3

If x = 3

LM = 3x + 5

= (3*3) + 5

= 9 + 5

= 14

Julia has to mow two yards she will need 13/16 gallon of gas to mow the first yard and 2/5 gallon to mow the second yard she has

Mazyrski [523]

Answer:

Julia has enough gas to mow the two yards.

Step-by-step explanation:

Given:

Julia needs $\frac{13}{16}$ gallon of gas to mow first yard.

Julia needs $\frac{2}{5}$ gallon of gas to mow second yard.

Julia has a total of $1\frac{1}{2}$ gallon of gas in in her can.

To find whether she has enough to mow both yards.

Solution:

Total gallons of gas needed to mow two yards can be found out by :

⇒ $\frac{13}{16}+\frac{2}{5}$

Taking LCD =80.

⇒ $\frac{13\times 5}{16\times 5}+\frac{2\times 16}{5\times 16}$

⇒ $\frac{65}{80}+\frac{32}{80}$

Adding the numerators.

⇒ $\frac{97}{80}$

⇒ 1.2125 gallons

Julia has $1\frac{1}{2}$ gallon = 1.5 gallons of gas in in her can.

Since $1.5>1.21$ , thus we can say that Julia has enough gas to mow the two yards.

(-6,-4) and is parallel to the line x+6y=12

HACTEHA [7]

Answer: y = $-\frac{1}{6}x-5$

Step-by-step explanation:

x+6y=12

6y=-x+12

y=- $\frac{x}{6}$ + 2

If its parallel it means that the slope will be the same

y = mx + b

-4 = -1/6 * (-6) + b

b = -5

Thus,

y = -1/6 x - 5

When performing a horizontal analysis on an income statement, the percentage change in any individual item is calculated by div

oksian1 [2.3K]

Answer: C. the base period amount.

Explanation: While implementing a horizontal analysis on a given income statement, we compute a percentage change in any individual item by dividing the dollar amount of change from base to current time period with the base period amount.

i.e. % Change in Individual item = $\frac{Current\ Dollar\ - Base\ Dollar }{Base \ period \ amount}$

Therefore, the correct option in this case is (c)
