Linear equations d-7=8

Mathematics
1 answer:
lukranit [14]3 years ago
4 0

Answer:

\boxed{ \boxed{ \bold{ \sf{d = 15}}}}

Step-by-step explanation:

\sf{d - 7 = 8}

Move constant to right hand side and change it's sign

⇒\sf{d = 8 + 7}

Add the numbers

⇒\sf{d = 15}

<u>Let's </u><u>check</u><u>:</u>

When d = 15 , R.H.S = 15 - 7 = 8

And L.H.S = 8

Thus , R.H.S = L.H.S when d = 15.

Therefore d = 15 is the solution of the equation.

Hope I helped!

Best regards!

Whats 3.2r + 14.7=6.74
Nata [24]

<u><em>r=-199/80 is the right answer.</em></u> First, you had to multiply by 100 from both sides of the equation. And it gave us, 3.2r*100+14.7*100=6.74*100. Next, you had to refine, and it gave us, 320r+1470=674. Then, subtract by 1470 from both sides of equation. And it gave us, 320r+1470-1470=674-1470. Simplify, and it gave us, 320r=-796. You can also divide by 320 from both sides of equation. And it gave us, \frac{320r}{320}=\frac{-796}{320}. And finally, simplify, and it gave us the answer is <em><u>r=-199/80 is the right answer.</u></em> Hope this helps! And thank you for posting your question at here on brainly. And have a great day! -Charlie

Svetach [21]

Answer: He will practice both on every 15 days.

Step-by-step explanation:

Given: Jaquan practices soccer every 3 days.

He practices basketball every 5 days Jaquan practiced both today.

The number of days until he practices both = Least common multiple of 3 and 5

= 15

Hence, he will practice both on every 15 days.

  • Least common multiple  of two numbers p and  q is the smallest number that is divisible by both p and q.
