<h3>Given Equation:</h3>
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
<h3>To Find:</h3>
The value of x and y.
<h3>Solution:</h3>
By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, <u>x = 0</u> ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, <u>y = </u><u>-</u><u>7/</u><u>3</u>
<h2>Answer: ( 0, -7/3 )</h2>
The value of x and y is 0 and -7/3 respectively.
Answer:
12.5g for 1 cake, 150g for 12 cakes
Step-by-step explanation:
Because you need 150g for 12 cakes so 1 cake will take:
150 / 12 = 12.5g
So, You need 12.5g for 1 cake
Hope this help :3
Area of square = atleast 36 = length *width, where l = w (since it's a square)
If A=36, l = w = 6
If A = 37, l = w = 6.08
if A =38, l = w = 6.16
So the solution set is s => 6 (s is bigger than or equal to 6)
Answer:
1/7
Step-by-step explanation:
There are 52 weeks in a year. Each have one Monday. Leap years have a total of 366 days. There are 7 days of the week. Monday is one of them, so it'll be a 1/7 chance.

Answer: </h3>
======================================================
Explanation:
Check out the diagram below.
I have drawn out two number lines with the key points 28,91,93,94 marked on them. The diagram isn't to scale, but that doesn't matter. All that matters is that the numbers line up (eg: we have the two 28's line up vertically).
The first number line drawing on top shows the shading for set A. Everything in the shaded region is either smaller than 91, or larger than 93, or 93 itself. We exclude 91 due to the curved parenthesis. The square bracket says to include the 93.
For the second graph, you have two endpoints as open holes (to exclude both endpoints) and you shade everything between.
-----------
After you draw the two number line regions, you would then mark off the interval(s) that they share in common.
The notation means "A intersect B" which means we want to find the stuff that is in both sets at the same time.
So we'll have two pieces here. The portion from 28 to 91 is the first interval, and then the second portion runs from 93 to 94. For each interval sub-piece, the endpoints are excluded
So that leads to the final answer
