Answer:

-1711005

Step-by-step explanation:

using BODMAS that implies you multiplication(M),before addition(A), then substraction(S) which comes last.

use the above rule to get the variable without letter only.

so ( 2*2)+(-3)=1

then 1-9=8, this part is for the left hand side which gives us 4x-8.

then the right hañd side 3-173-5133193 not including the variable with the letter x.now we have:1x-5133023.

so now

4x-8=1x-5133023

collect like terms

4x-1x=-5133023+8

3x=-5133015

divide both side by 3

x= -1711005

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

joja [24]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple

The measure of one angle of a right triangle is 56∘ more than the measure of the smallest angle. Find the measure of the smalles

GrogVix [38]

Answer:

The sum of all angels for any triangle equals 180°

so we have a right triangle which means we have an angle equals 90° ,angle equals=56°.

step by step

$180 - 56 - 90 = 34$

so the angle tends to equal 34°.

Find the length of WR<br><br>If M <WCR = 49 and CR = 7. What is WR

UkoKoshka [18]

We know that
if ∠WCR=49°
then
measure arc WR=49°-------> by central angle

circumference C=2*pi*r
for r=7 in
C=2*pi*7-----> 43.96 in

if 360°(full circle) has a length of----------> 43.96 in
49°---------------> x
x=49*43.96/360-----> x=5.98 in

alternative method
applying the formula
L=(∅/360°)*2*pi*r
where
∅ is the angle in degrees
r is the radius
L=(49°/360°)*2*pi*7------> L=5.98 in

the answer is
5.98 in
