How to cross multiple 3/5 by 10

Mathematics
1 answer:
Vika [28.1K]3 years ago
4 0

Here is you're answer:

In order to cross multiply you have to multiply the numerator and denominator of the first fraction by the bottom number of the second fraction and see if the equation is still true:

  • \frac{3}{5} \times 10
  • \frac{3}{5} \times \frac{10}{1}
  • 3 \times 1 = 5 \times 10
  • Solve if you like:
  • 3 \times 1 = 3
  • 5 \times 10 = 50
  • = \frac{4}{50}

Therefore you're answer is "3 × 1 = 5 × 10."

Hope this helps!

Answer:

The domain of f is {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

Step-by-step explanation:

<em>The domain of a function is </em><em>all the values of x</em><em> make the function defined</em>

In the given graph

∵ The graph drawn from x = -7 to x = 7 and from y = -6 to y = 4

→ That means the values of x started from -7 and ended at x = 7

∵ The coordinates of the starting point of the graph of f are (-7, -5)

∵ The coordinates of the ending point of the graph of f are (7, 3)

∴ -7 ≤ x ≤ 7

∵ Values of x are the domain of the function

∴ The domain of the function is -7 ≤ x ≤ 7

∴ The domain of f = {x : x ∈ R, -7 ≤ x ≤ 7} ⇒ [-7, 7]

Perform the operation.<br> (-x^2 – 1) – (-2x^2 – 4)
ivolga24 [154]

Answer:

Okay!

Step-by-step explanation:

I have simplified the operation, and I got x^2 + 3.

If you wanted me to evaluate, the answer is still  x^2 + 3.

If you wanted me to subtract then the answer is again,  x^2 + 3.

Basically the answer is  x^2 + 3.

Have a good day!

Give all solutions if the nonlinear system of equations, including those with no real complex components.
konstantin123 [22]
\left\{\begin{array}{ccc}y=x^2+6x\\4x-y=-24\end{array}\right\\\\substitute:\\\\4x-(x^2+6x)=-24\\\\4x-x^2-6x+24=0\\\\-x^2-2x+24=0\\\\a=-1;\ b=-2;\ c=24\\\\\Delta=b^2-4ac

\Delta=(-2)^2-4\cdot(-1)\cdot24=4+96=100\\\\x_1=\frac{-b-\sqrt\Delta}{2a};\ x_2=\frac{-b+\sqrt\Delta}{2a}\\\\\sqrt\Delta=\sqrt{100}=10\\\\x_1=\frac{2-10}{2\cdot(-1)}=\frac{-8}{-2}=4;\ x_2=\frac{2+10}{2\cdot(-1)}=\frac{12}{-2}=-6\\\\y_1=4^2+6\cdot4=16+24=40;\ y_2=(-6)^2+6\cdot(-6)=36-36=0\\\\Answer:\\x=4\ and\ y=40\ or\ x=-6\ and\ y=0

If KL = LM and KJ = JM, find m ∠KJL<br><br> please, i really need your help!
umka2103 [35]
The triangles are congruent by SAS, so the two angles with 7x and 3x+16 are equal. So

7x=3x+16
4x=16
x=4

So KJL=7(4)=28.

The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew
Nesterboy [21]

Answer:

£910

Step-by-step explanation:

let 3x and 7x be the initial amounts in their accounts, then after alterations

Terry has 3x + 220

Faye has 7x - 300

After these changes the amounts are equal, hence

7x - 300 = 3x + 220 ( subtract 3x from both sides )

4x - 300 = 220 ( add 300 to both sides )

4x = 520 ( divide both sides by 4 )

x = 130

Faye initially had 7 × £130 = £910 in her account
