Which equation matches the statement below?

kvasek [131]

Answer:

3(n-5)=2n+16

Step-by-step explanation:

3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)

3(5 - n)

16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have

2n + 16

if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.

3(n-5) = 2n+16

6m−7)⋅4=left parenthesis, 6, m, minus, 7, right parenthesis, dot, 4, equals ¿Atorado?

mars1129 [50]

Answer:

24m - 28

Step-by-step explanation:

Given the expression (6m−7)⋅4, we are to simplify it. Using the distributive law;

A(B+C) = AB + AC [A is distributed over B and C]

For the expression (6m−7)⋅4, we will distribute 4 over 6m and -7 as shown;

(6m−7)⋅4 = 4(6m) - 4(7)

(6m−7)⋅4 = 24m - 28

Hence (6m−7)⋅4 = 24m - 28

Answer:

The required equation is $\frac{3}{2}x-3=y$

Step-by-step explanation:

The equation of the given function can be written in the form $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

The given equation has a y-intercept of $b=-3$

The straight line passes through $(0,-3)$ and $(2,0)$ .

We calculate the slope using the formula,

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{0--3}{2-0}$

$m=\frac{0+3}{2-0}$

$m=\frac{3}{2}$

We now substitute the slope and y-intercept into the above equation of the straight line to get,

$y=\frac{3}{2}x-3$

This is the same as

$\frac{3}{2}x-3=y$

My name is Ann [436]

Answer:

A and B

Step-by-step explanation:

Given

$Nuts = 28\ bags$

$Fruit = 21\ bags$

Required

Determine the appropriate combination

First, we need to determine the factors of 28 and 21

$28: 1 * 28; \\28: 2 * 14; \\28: 4 * 7$

$21: 1 * 21; \\21: 3 * 7$

Next, is to bring out the similar traits in both factors

$28: 1 * 28; \\28: 4 * 7$

$21: 1 * 21; \\21: 3 * 7$

Represent both in terms of bag, we have:

1 bag of 28 nuts

7 bags of 4 nuts

1 bag of 21 dried fruits

7 bags of 3 dried fruits

This gives:

1 bag of 28 nuts and 1 bag of 21 dried fruits

7 bags of 4 nuts and 7 bags of 3 dried fruits

Hence:

<em>Option A and B are correct</em>
