A landscaper needs 348 pounds of plant food. He has 114 pounds in his truck, and another 46 pound at his shop.

andrew-mc [135]

Answer:

$\frac{19}{12}\ pounds$

$1\frac{7}{12}\ pounds$

Step-by-step explanation:

<u><em>The correct question is </em></u>

A landscaper needs 3 4/8 pounds of plant food. He has 1 1/4 pounds in his truck, and another 4/6 pound at his shop. How many more pounds of plant food does the landscaper need?

Let

x ----> the additional pounds of plant food needed for the landscaper

we know that

The additional pounds of plant food needed for the landscaper plus the pounds in his truck plus the pounds in his shop must be equal to the total pounds of plant food needed

The linear equation that represent this problem is

$x+1\frac{1}{4}+\frac{4}{6}=3\frac{4}{8}$

Convert mixed number to an improper fractions

$1\frac{1}{4}=1+\frac{1}{4}=\frac{4*1+1}{4}=\frac{5}{4}$

$3\frac{4}{8}=3+\frac{4}{8}=\frac{3*8+4}{8}=\frac{28}{8}=\frac{14}{4}$

Substitute in the expression above

$x+\frac{5}{4}+\frac{4}{6}=\frac{14}{4}$

solve for x

Multiply by (4*6) both sides to remove the fractions

$24x+30+16=84$

Combine like terms left side

$24x+46=84$

subtract 46 both sides

$24x=84-46$

$24x=38$

Divide by 24 both sides

$x=\frac{38}{24}\ pounds$

simplify

$x=\frac{19}{12}\ pounds$

Convert to mixed number

$\frac{19}{12}\ pounds=\frac{12}{12}+\frac{7}{12}=1\frac{7}{12}\ pounds$

– 3х – бу = 17; (6, 3)

almond37 [142]

I'm going to assume that you want to know whether the coordinate satisfies the equation. Let's find out;

-3х - 6у = 17

-3(6) - 6(3) = 17

-18 - 18 = 17

-36 ≠ 17

The point (6, 3) does NOT satisfy the equation.

Best of Luck!

In circle p, td¯¯¯¯¯ and tb¯¯¯¯¯ intersect at t. ta=10, tc=8, cd=12, and ab=x+2. find ab. circle p. answer

inysia [295]

The answer is AB = 6.

External value x (external value + internal value) =
External value x (external value + internal value) of the other side

Substitute, transpose, and simplify.

TA x (TA + AB) = TC x (TC + CD)
10 x (10 + (x + 2)) = 8 x (8 + 12)
120 + 10x = 160
10x = 40
x = 4

To find AB: x + 12; x = 4
AB = x + 2
AB = 4 + 2
AB = 6

Decide whether each expression is equal to 6 x 3/4. Write an X in the table to respond.

Tomtit [17]

Answer:

6 × ¼ is NOT EQUAL TO 6 × ¾

8 × ²/4 is NOT EQUAL TO 6 × ¾

18/(2 × 2) is EQUAL TO 6 × ¾

Step-by-step explanation:

Given 6 * ¾,

We're asked to determine if each of the given expressions is equal or not equal to 6 * ¾.

Let's evaluate 6 * ¾

6 × ¾ = (6×3)/4 = 18/4 = 4.5

Now, let's compare each expression given to determine if it is equal or not

✔️6 × ¼ = (6×1)/4 = 6/4 = 1.5

Therefore,

6 × ¼ is NOT EQUAL TO 6 × ¾

✔️8 × ²/4 = (8×2)/4 = 16/4 = 4

Therefore,

8 × ²/4 is NOT EQUAL TO 6 × ¾

✔️18/(2 × 2) = 18/4 = 4.5

Therefore,

18/(2 × 2) is EQUAL TO 6 × ¾
