There are more than 15 shapes all together but no more than 25. There are 6 more squares than circles. There are 7 fewer circles

Ugo [173]

Answer:

the number of circles is 3

the number of square is 9

the number of triangle is 10

Step-by-step explanation:

Let the number of square = s

let the number of circle = c

let the number of triangle = t

let the total number of the shapes = y

15 < y < 25

y = s + c + t ---- (i)

s = c + 6 ------ (ii)

c + 7 = t ------ (iii)

y = (s) + (c) + (t)

y = (c + 6) + (c) + (c + 7)

y = 3c + 13

15 < y < 25

15 < 3c + 13 < 25

15 - 13 < 3c < 25 -13

2 < 3c < 12

2/3 < c < 12/3

0.67 < c < 4

Thus, number of circle is greater 1 but less than 4

c = 3

s = 3 + 6 = 9

t = 3 + 7 = 10

Caitlyn needs to solve the equation: 2(3x+1)=3(2-x).

Mila [183]

Step 1:Simplify both sides of the equation.2(3x+1)=3(2−x)(2)(3x)+(2)(1)=(3)(2)+(3)(−x)(Distribute)6x+2=6+−3x6x+2=−3x+6
Step 2: Add 3x to both sides.6x+2+3x=−3x+6+3x9x+2=6
Step 3:Subtract 2 from both sides.9x+2−2=6−29x=4
Step 4:Divide both sides by 9.9x9=49

hope it helps :)

The given line passes through the points (-2,-4) and (2,2) What is the equation, in point-slope form, of the line that is parall

Morgarella [4.7K]

Answer:

$(y-1)=\frac{3}{2}(x+3)$

Step-by-step explanation:

The point slope form of a line is $(y-y_1)=m(x-x_1)$ where $x_1=-3\\y_1=1$ . We write

$(y-1)=m(x--3)\\(y-1)=m(x+3)$

Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.

$(y-1)=\frac{3}{2}(x+3)$

The sum of the measures of two complementary angles exceeds the difference of their measure by 86_. Find the measure of each ang

Bad White [126]

As the sum of two complementary angles = a + b = 90 degree -------(1)

Difference of two complementary angles = a – b

According to question;

The difference of two complementary angles exceed the sume (90) by 86.

a – b = 90 – 86 = 4 -------(2)

adding equation (1) and (2);

2a = 90 + 4 = 94

a = 94 / 2 = 47

putting a = 47 in equation (1);

47 + b = 90

b = 90 – 47 = 43

So angle a = 47 and angle b = 43
