What is the value of X? (8y+12) (7x+4)​

Mathematics

Answer:

The value of x is -\frac{4}{7}

Step by step explanation:

In the question we are given a product that contains two unknown variables, i.e. x and y. To solve for x we shall first compute the product between the two brackets. I will show each step in full detail, in order to understand the product computation of such cases (i.e. distributive property).

(8y+12)(7x+4)=0\\\\8y*7x+4*8y+12*7x+12*4=0\\\\56xy+32y+84x+48=0\\\\

Up to this point we have computed the product and now we have all our terms. Since we want to find the value of x we will gather together all terms that contain x (even if they also contain y) and then do some manipulations and simplifications to obtain our result, as follow:

56xy+32y+84x+48=0\\\\56xy+84x=-32y-48\\\\14x(4y+6)=-8(4y+6)

Now we see that on both sides of the equality we have a common term of   (4y+6), which we can cancel out from both sides, which leaves us with:

14x=-8\\\\x=-\frac{8}{14}\\\\ x=-\frac{4}{7}

Thus the value of x is -\frac{4}{7}.

If the volume of the bat is 82
Assoli18 [71]

The volume that is left to be filled is approximately: 3,332.6 in.³

<h3>What is the Volume of a Box?</h3>

Volume of a box = (length)(width)(height)

Given the following:

Volume of the bat = 82 cubic in.

Length of box = 30 in.

Width = 18.97 in.

Height = 6 in.

The remaining volume to be filled = volume of box - volume of bat

= (30)(18.97)(6) - 82

= 3,332.6 in.³

goldfiish [28.3K]

Answer:

2,196;    549;     131.76;     8;     175.68;      1339.56

Step-by-step explanation:

2,196 is the biggest number, so use that as the first number.

.25x2196=549

.06x2196=131.76

.08x2196=175.68

2196-(549+131.76+175.68)=1339.56

PLZ HURRY WILL MARK BRAINLIEST The stem and leaf plot shows the number of points a basketball team scored each game during its 1
oee [108]

Answer:

5 games

Step-by-step explanation:

To find how many games the team scored at least 70 points, we need to look at the 7 on the stem side. The 7 means 70, and we add the digits on the leaf side. For example, 7 | 2 is 72. The numbers on the leaf side are: 1, 1, 2, and 3.

There are no points for the 8 on the stem side, but on 90, there is one digit on the leaf side: 1. So, the points they scored over 70 are 71, 71, 72, 73, and 91, which equals to five games.
