Write and solve a system of linear​ equations: The larger of two numbers is 18 more than 5 times

Mathematics
1 answer:
Kryger [21]2 years ago
8 0

Answer:

8 and - 2

Step-by-step explanation:

let x be the larger number and y the smaller , then

x = 5y + 18 → (1)

3x + 4y = 16 → (2)

substitute x = 5y + 18 into (2)

3(5y + 18) + 4y = 16 ← distribute parenthesis and simplify left side

15y + 54 + 4y = 16

19y + 54 = 16 ( subtract 54 from both sides )

19y = - 38 ( divide both sides by - 19 )

y = - 2

substitute y = - 2 into (1)

x = 5(- 2) + 18 = - 10 + 18 = 8

then larger number is 8 and smaller is - 2

Write an inequality relating NM and NL-<br> NM &lt; NL<br> NM&lt;_ NL<br> NM &gt; NL<br> NM&gt;_ NL
spayn [35]

Answer:

NM > LN

Step-by-step explanation:

Here, we want to write an inequality

we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively

as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;

So we can conclude that;

NM > LN

Everett made 3/5 of the baskets he shot suppose he shot 60 baskets how many did he make
givi [52]
As given he made  3/5 of basket he shot.

So we can find number of basket made by Everett equal to 3/5 of total number of shot .

So if total number of shot is 60.

Then the number of basket made by Everett = \frac{3}{5} of 60.
                                                                            \frac{3}{5} * 60 =  \frac{3 * 60}{5} =  \frac{180}{5} = 36

So the number of basket made by Everett in 60 shots = 36.
