can someone please help me with numbers 11 12 13 and 14 please , and can you please explain how you got the answer?
Answer:
11) x = 4
12) x = 12
13) A = 45
14) A = 40
Step-by-step explanation:
All triangle angles must add up to 180 degrees. If they do not, the triangle is not considered a triangle.
So for triangle 11, solve using the equation: (16x + 4) + 47 + 65 = 180. First add 47 + 65 together to get 112. Subtract 112 from both sides to get (16x + 4) = 68. Subtract 4 from both sides to get 16x = 64. Divide 16 from both sides to get x = 4. Use the same technique for the other triangle.
For triangle 12, solve using the equation: (3x + 9) + 60 + 75 = 180. Add 60 + 75 to get 135. Subtract 135 from both sides to get (3x + 9) = 45. Subtract 9 from both sides to get 3x = 36. Divide 3 from both sides to get x = 12.
For triangle 13, solve using the equation: (62 + x) + (x + 51) + 79 = 180. For this equation, add the common variable first to get 113 + 2x + 79 = 180. You can still further simplify by adding 113 + 79 to get 192. The new equation is 192 + 2x = 180. Subtract 192 from both sides to get 2x = -12. Divide 2 from both sides to get x = -6. Now, to solve for angle A, insert the x value, -6, into Angle A's expression: x + 51. The x value would change the expression into -6 + 51. Solve to get 45. Use this technique for the other triangle as well.
For triangle 14, solve using the equation: 6x + 4x + 80 = 180. First add common variables to get 10x + 80 = 180. Subtract 80 from both sides to get 10x = 100. Divide both sides by 10 to get x = 10. To solve for Angle A, insert the x value, 10, in place of x. This turns the expression 4x into 4(10). Solve to get 40.

Hi guys can you answer my math question
Answer:
(a) 7 + 4 = 11
(b) 1 + 3 + 5 = 9
(c) (7 x 2) + 1 = 15
(d) (7 x 2) - 1 = 13
(e) 13 - 9 = 4
Step-by-step explanation:
(a) 5 + 4 = 9
(b) 7 + 1 + 11 = 19
(c) 25 = 12 + 12 + 1
(d) 7 = 4 + 4 - 1
(e) 13 - 11 = 2
Four families share a basket of 16 kilograms equally how many kilograms of apples does each family get?
Answer:
4 kg of apples
Step-by-step explanation:
Given that,
Number of families = 4
Weight of the basket of apples= 16 kg
We need to find how many kilograms of apples does each family gets. We can find it as follows :
Received = [tex]\dfrac{16}{4}[/tex] = 4 kg of apples
Hence, each family gets 4 kg of apples.
What is the slope of the line that travels through the origin?
Answer: The answer is 0 (An undefined slope)
Step-by-step explanation: The answer would be 0 but you can not just use 0 you have to use math terms. So in math terms undefined slope is o. ALSO if the line is Horizontal its o and if the line is Vertical it is undefined.
NOTE: 0 AND UNDEFINED iS NOT THE SAME THING

There are 10 students in a class:7 boys and 3 girls. If the teacher picks a group of 4 at random what is the probability that everyone in the group is a boy
Answer:
Step-by-step explanation:
Probability the first pick is a girl: 7/10
Probability the second pick is a girl: 6/9
Probability the third pick is a girl: 5/8
Probability of picking 3 girls:
7/10 * 6/9 * 5/8 =
= (7 * 6 * 5)/(10 * 9 * 8)
= (7 * 1 * 1)/(2 * 3 * 4)
=7/24

The function below shows the cost of a hamburger with different numbers of toppings (t). f(t) = 1.90 + 1.40t What is the y-intercept, and what does it mean?
Answer:
[tex]1.9[/tex]
the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.
Step-by-step explanation:
The function is
[tex]f(t)=1.9+1.4t[/tex]
Let cost of toppings be [tex]y[/tex]
[tex]y=1.9+1.4t[/tex]
The y-intercept of a function is the value of the function when [tex]x=0[/tex]. Here number of toppings [tex]t=0[/tex].
So, the intercept of the function is [tex]1.9[/tex]
This means the cost of the hamburger will be [tex]\$1.9[/tex] if no toppings are added.

Step-by-step explanation:
At the deli, 2 turkey subs and 5 veggie subs cost $29. 4 turkey subs and 3 veggie subs cost
$30.
a) Create a linear system to model the equation. Include let statements
b) Solve the linear system to find the cost of a turkey sub and the cost of a veggie sub.
Answer:
4/9 of sales are veggie 5/9 are turkey
4/(4+5)=4/9
5/(4+5)= 5/9
4/9 x 27 = 12
5/9 x 27 = 15
12 veggie subs sold and
15 turkey subs sold
12+15=27 total sold
