Answer:

hence solution for x in the equation is x= 1/2

Step-by-step explanation:

4x - 3+5 = 2x + 7 - 8x

4x +2 = -6x +7

taking x to the other side then we get

4x+6x = -2+7

10x = 5

divide both side by 10

10x/10 =5/10

x= 1/2

hence solution for x in the equation is x= 1/2

Albert receives $0.30 per pound for 1 to 49 pounds of glass bottles he recycles. He receives $0.40

Marina86 [1]

Answer:

Yes

Step-by-step explanation:

The amount of money Albert receives is described by the expression

$y = \begin{cases}0.30x & \quad \text{if } 0 \leq x \leq 49 \\0.40x & \quad \text{if } x > 50\\\end{cases}$

The graph is shown below.

To determine if the relation is a function, we can use the vertical line test:

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

How do I solve this math question? give full explanation using a formula.

lukranit [14]

Answer:

30 short cakes

Step-by-step explanation:

25ml = 10ml + 10ml +5ml

each 10ml of milk can make us 12 short cakes

we can two 10ml of milk (20ml) which can make us 24 short cakes.

but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?

5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.

25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)

After dinner 2/3 of a pan of lasagna is left. The hole pan of Lasagna was originally cut in into pieces that were each 1/6 of th

Paraphin [41]

Answer:

An equation represents the number of pieces of lasagna that are left after dinner is $\frac{1}{6}x=\frac{2}{3}$

Step-by-step explanation:

Each piece of Lasagna is 1/6 of the pan

Let x be the number of pieces left

So, x pieces is $\frac{1}{6}x$ of the pan

We are given that After dinner 2/3 of a pan of lasagna is left.

So, $\frac{1}{6}x=\frac{2}{3}$

$x=\frac{2}{3} \times 6$

x=4

So, Number of pieces left = 4

Hence An equation represents the number of pieces of lasagna that are left after dinner is $\frac{1}{6}x=\frac{2}{3}$
