$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: 2m - 3 - 5 = - m + 10$

$\qquad \sf \dashrightarrow \: 2m + m = 10 + 3 + 5$

$\qquad \sf \dashrightarrow \: 3m = 18$

$\qquad \sf \dashrightarrow \: m = 18 \div 3$

$\qquad \sf \dashrightarrow \: m = 6$

Hence, value of m is 6

Pairs that satisfy function y=2x+1

evablogger [386]

Test a pair from each table by substituting their values into the given equation and solving.

A) y = 2x + 1 .......... 2 = 2(0) + 1 .......... 2 ≠ 1

B) y = 2x + 1 .......... 1 = 2(0) + 1 .......... 1 = 1

C) y = 2x + 1 .......... -1 = 2(0) + 1 .......... -1 ≠ 1

D) y = 2x + 1 .......... -2 = 2(0) + 1 .......... -2 ≠ 1

The only pair that satisfied the equation was from answer choice B. Therefore, B is the correct answer.

Please help me!

Zigmanuir [339]

Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

$(\frac{2}{3}s + \frac{5}{6}s) = 21$
$(\frac{4}{6}s + \frac{5}{6}s) = 21$
$\frac{9}{6}s = 21$
$\frac{3}{2}s=21$

Step 2: Multiply both sides by 2/3.

$\frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}$
$s = \frac{42}{3}$
$s = 14$

Can someone remind me how to add negative and positive numbers together along with subtracting them correctly? Please provide ex

Zarrin [17]

To add a negative and a positive I usually just subtract them so ex: -5+4=-1
and to subtract them I add the numbers together so -5-4=-9 so its basically the opposite

Isosceles JAM has convex angle M. JM=35,MA=4n+3, angle J=14w-1, and angle m=98 Find n. Find w. Find the perimeter of JAM

Lena [83]

Answer:

n = 8, w = 3 and perimeter = 122.83 units.

Step-by-step explanation:

Let the angle M is the angle between the equal sides of isosceles JAM.

So, JM = MA

⇒ 35 = 4n + 3

⇒ 4n = 32

⇒ n = 8 (Answer)

Now, if ∠ J = 14w - 1 and ∠ M = 98°, then

2(14w - 1) + 98 = 180

⇒ 2(14w - 1) = 82

⇒ 14w - 1 = 41

⇒ w = 3 (Answer)

Now, draw a perpendicular bisector on JA from vertex M and it meets JA at P say.

So, Δ MPJ will be a right triangle with ∠ J = (14w - 1) = 41° {Since w = 3}

Hence, $\cos 41 = \frac{JP}{JM} = \frac{JP}{35}$

⇒ JP = 35 cos 41 = 26.415

So, JA = 2 × JP = 52.83

So, the perimeter of Δ JAM is = 35 × 2 + 52.83 = 122.83 units (Answer)

Carly drove 617.3 miles his car get about 41 miles per gallon which is the best estimate of how many gallons of gas Carly used

Lerok [7]

Answer:

He used about 15 gallons

Step-by-step explanation: if he drove 617.3 miles and he gets 41 miles per gallon, then we can use the formula 41x=617.3 to solve this formula, we would divide 617.3 by 41 to isolate x. 617.3 divided by 41 is equal to 15 and therefore x = 15
