This angle is divided into two angles.

Because of this, we know that m angle CKL plus the m angle JKC will equal the total degrees in the larger angle (JKL)

Simply subtract the known angle of 74 degrees from 122 degrees to get the measure of angle JKC.

122-74 = 48

ANSWER:
m angle JKC = 48 degrees

Measure angle JKC + measure angle CKL = measure angle JKL

measure angle JKL = 122 and measure angle CKL = 74
Substitute wuth these values in the equation to get measure angle JKC where:
JKC + 74 = 122
measure angle JKC = 122 - 74

A jar contains sugar. The jar and the sugar have a total weight of 850 g. Anna uses 2/3 of the sugar. The jar and the sugar now

maria [59]

Answer:

$J = 370g$

Step-by-step explanation:

Given

Represent the weight of the Jar with J and the sugar with S

Initially, we have:

$J + S = 850g$

After 2/3 of sugar is removed we have:

$J + S -\frac{2}{3}S= 530g$

Required

Determine the weight of the jar

$J + S = 850g$ --- (1)

$J + S -\frac{2}{3}S= 530g$ --- (2)

Simplify (2)

$J + S -\frac{2S}{3}= 530g$

Take LCM

$J + \frac{3S - 2S}{3}= 530g$

$J + \frac{S}{3}= 530g$

Make S the subject in (1)

$J + S = 850g$

$S = 850g - J$

Substitute 850g - J for S in $J + \frac{S}{3}= 530g$

$J + \frac{850g - J}{3}= 530g$

Multiply through by 3

$3 * J + 3*\frac{850g - J}{3}= 530g * 3$

$3J + 850g - J= 1590g$

Collect Like Terms

$3J - J= 1590g-850g$

$2J= 740g$

Make J the subject

$J = \frac{1}{2} * 740g$

$J = 370g$

<em>The jar weighs 370g</em>

Factor completely 3x^2+2x-1

Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)

In the past Reagan got paid 214,350 annually. Since switching to a new career she has been making 347,247 annually. What is the

Dima020 [189]

Answer: Reagan's pay was increased by 62%

Step-by-step explanation:

First, lets find the difference between the two pays:

$347,247 - $214,350 = $132,897

Let 214350 = 100%

Dividing 132,897 by 214350 to find the percent increase

$\bold{\frac{132,897}{214,350} }=0.62\times100=62$

Therefore, Reagan's pay was increased by 62%
