Make x the subject of the following: b = x - 5

When it says "the subject", it only means you need to isolate the x, or solve for x. To do that, we have to get the x by itself. But how can we do that? We'll have to get rid of that pesky -5. Well, what can we do to -5 to get to 0? Of course -- Add 5!
b=x-5
+5

But whatever we do to one side of the equation, we have to do to the other.
b=x-5
+5 +5

We're left with b+5=x. There's your answer!

Which problem is solved using this model? 15÷15 3÷115 3÷15 15÷15 https://static.k12.com/nextgen_media/assets/1503272-MAT

Pie

Answer:

As the model is shown below.

As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.

The value of fifth part of each of them is 1/5.

If we consider each part of a thing as one,

So, total number of parts = 15

Total thing=3

So, the answer of the above model is 3÷ 15.

Out of all the options which are 15÷15 , 3÷115 , 3÷15, 15÷15 →3÷15 is correct.

Carlos has scored 83, 81, and 73 on his previous three tests. What score does he need on his next test so that his average (mean

disa [49]

Answer:

95

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = $\frac{83+81+73+x}{4}$ = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Find x<br> a) 21 √2<br> b)7<br> c)21 √2/2<br> d)21 √3/2

fgiga [73]

Answer:

C

Step-by-step explanation:

Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values

sin60° = $\frac{\sqrt{3} }{2}$ , cos45° = $\frac{1}{\sqrt{2} }$ , thus

sin60° = $\frac{opposite}{hypotenuse}$ = $\frac{opp}{7\sqrt{3} }$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2 × opp = 21 ( divide both sides by 2 )

opp = $\frac{21}{2}$

Now consider the right triangle on the right, using the cosine ratio

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{\frac{21}{2} }{x}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x = $\frac{21}{2}$ × $\sqrt{2}$ = $\frac{21\sqrt{2} }{2}$ → C
