Answer:

32 polo, 28 measles

Step-by-step explanation:

4p + 2m = 184 <-- doses

p + m = 60 <-- vaccines

solve:

4p + 2m = 184

-2p - 2m = -120 <-- multiplied both sides by -2

------------------------

2p = 64

p = 32

plug back in:

32 + m = 60

p = 32

m = 28

Solve for the variable a D =a+b-c/3

yuradex [85]

Hey there,
solving for a is just like you think of all other letter as a constant
i.e the only variable is a
so you need to subtract b as a start
d=a+b-c/3
-b -b
=============

-b+d=a-c/3 now it's time to add c/3 (isolate a by itself in one side)

-b+d=a-c/3
+c/3 +c/3
==============
c/3-b+d=a

Hence you have solved for a

What is the Value of x+y ? PLZ Help ASAP

Natalija [7]

ANSWER

$x + y = 60$

EXPLANATION

Method 1

Vertically opposite angles are equal, therefore

$3x + 55 = 85$

This implies that,

$3x = 85 - 55$

We simplify to get,

$3x = 30$

Dividing through by 3 gives,

$x = 10$

Also,

$2y - 5 = 95$

This implies that,

$2x = 95 + 5$

We simplify the right hand side to get,

$2x = 100$

We divide both sides both sides by 2 to get,

$x = 50$

$x + y = 50 + 10$

$x + y = 60$

Method 2

Angles on straight line sums to 180°.

$2y-5+85=180$

This implies that,

$2y+80=180$

$2y=180-80$

$2y=100$

$y=50$

Also,

$3x+55+95=180$

$3x+150=180$

$3x=180-150$

$3x=30$

$x=10$

$x+y=50+10$

$x+y=60$

7. A study reported that in a random sampling of 100 women over the age of 35 showed that 8 of the women were married 2 or more

Pavel [41]

Hi! The answer is going for be D (400)

Step-by-step explanation:

Out of 100 women, 8 were married 2 or more times which is 8% or 0.08

So out of 5000 women, the number of women married 2 or more times is: 0.08*5000 = 400

x/5000 = 8/100

x/50=8/1

x=400

Hope this helps! Have a good day!

Help me please I’ll give brainly

rodikova [14]

Answer: 55.0% decrease
Explanation: 100% =10
100% divided by 10 is 10%
10 divided by 10 is 1
So 1 is 10%
1 divided by 2 = 0.5 Is 10% divided by 2 = 5%
So 4.5 is 45%
100% - 45% = 55%
So there is a 55.0%decrease
