Answer:

Step-by-step explanation:

∠1 = (6x + 2)° (vertically opposite angles are equal)

15x + 10° +∠1 = 180° (co-interior angles are equal)

15x + 10° + 6x + 2° = 180°

15x + 6x + 10° + 2° = 180°

21x + 12° = 180°

21x = 180° - 12°

21x = 168°

x = 168/21

x = 8

Answer:

$\frac{1}{2}$ is the answer

Step-by-step explanation:

First we need to substitute X and Y with their respective numbers

$3\cdot \:6+\frac{6}{-4}-\left(-4\right)^2$

Then, following PEMDAS, We just need to simplify

$18+\frac{6}{-4} -16$

$16.5-16=0.5=\frac{1}{2}$

I’m really struggling with these proofs. We just started learning them and I’m highly confused!! Please help :)

I'm not sure about what exactly your teacher is looking for, but the actual congruency conjecture you would use is:

(angle symbol) 1 (congruency symbol) (angle symbol) 8 - Because they are alternate exterior angles

The expression i/pt represents the rate of instrest being charged if a loan of p dollars for t years required i dollars in intre

zysi [14]

Answer:

7.3%

Step-by-step explanation:

Given:

<em>Formula for Rate of interest </em> $R$ :

$R=\dfrac{i}{Pt}$

Where $i$ is the rate of interest.

$P$ dollars is the loan and

$t$ years is the time for which interest is to be paid

$P =\$690\\t=3\ years\\i=\$151.11$

To find:

$R=?$

Solution:

Putting the given values in the formula:

$R=\dfrac{151.11}{690 \times 3}\\\Rightarrow R=\dfrac{151.11}{2070}\\\Rightarrow R=0.073$

Multiply the above value with 100 to find the percentage.

i.e.

$R=0.073\times 100 = \bold{7.3\%}$

Therefore, the answer is <em>7.3%</em>

The students in the Go Green dub started a whool recling program. In

OlgaM077 [116]

Answer:

Students collected

$85+255=340$ pounds of paper;
$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.

Step-by-step explanation:

In September, the students collected 85 pounds of paper and 18 pounds of cans to recycle.

In October, their goal is to collect three times the amount of paper and five times the amount of cans they collected in September.

Hence, in October they collected

$85\times 3=255$ pounds of paper;
$18\times 5=90$ pounds of cans.

In total, they collected

$85+255=340$ pounds of paper;
$18+90=108$ pounds of cans;
$340+108=448$ pounds of paper and cans combined in September and October.
