Answer:

X=5

Step-by-step explanation:

3x-8=7

3x=15 (add 8 to both sides)

X=5 (divide by 3)

Since, x = 5
So,
3x - 8 = 7
or, 3 x 5 - 8 = 7
Therefore, 15 - 8 = 7

380 mangoes are distributed among some boys and girls who are 85 in numbers each boys get four mangoes and each girls get five t
yaroslaw [1]

Answer:

Boys(B) + Girls(G) = 85    ----(1)

Mangoes = 380

Each boy gets 4mangoes

Each girl gets 5mangoes

4B + 5G = 380   -------(2)

from (1) B = 85 - G

Substitute B in (2)

4(85 - G) + 5G = 380

360 - 4G + 5G = 380

G = 380 - 360 = 20

from (1) B = 85 - 20 = 65

Therefore number of boys = 65 and girls = 20

Ratio of boys and girls = 65 : 20 = 13 : 4

800+60+4 in standard form
alisha [4.7K]
<span>The answer is 864. The expanded form of a number is 800+60+4. The standard form of 800+60+4 will have three digits because the greatest number in expanded form has three digits. The first digit of the number in the standard form will be the number of hundreds which is 8 (800/100 = 8). The second digit of the number in the standard form will be the number of tens which is 6 (60/10 = 6). The third digit of the number in the standard form will be the number of ones which is 4 (4/1 = 4). So, 800+60+4 in the standard form is 864.</span>

The equation f(x)=x−5 translated 4 units to the left is g(x)=
elixir [45]

The equation of the function g(x) is g(x) = x - 1

<h3>How to determine the equation of the function g(x)?</h3>

The given parameters are:

f(x) = x - 5

The above function f(x) is translated left by 4 units

So, we have

g(x) = f(x + 4)

This gives

f(x + 4) = x + 4- 5

Evaluate the sum

f(x + 4) = x - 1

So, we have:

g(x) = x - 1

Hence, the equation of the function g(x) is g(x) = x - 1
