She is not correct because 3/7 + 1/2 = 13/14.
4/9 is not greater than 1/2.
6 dimes but you need change to make 68. You could use a nickel and and 3 pennies. Hope this helps and plz mark brainliest.
Answer:
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
Step-by-step explanation:
The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.
28x - 7 + 24x + 18 = 180
52x + 11 = 180
52x = 169
x = 169/52
x = 3.25
Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.
12y + 30 = 24x + 18
We know that x = 3.25.
12y + 30 = 24(3.25) + 18
12y + 30 = 78 + 18
12y = 66
y = 66/12
y = 5.5
I don't know what the problem is asking for since you don't show.
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
Answer:
14cm^2
Step-by-step explanation:
Area of a triangle is (base×height)/2
(4×7)/2
28/2
=14 centimetres squared
10.5*5= 52.5 is the correct answer to the question
