Answer:
she has a total of 140 coins
Step-by-step explanation:
x is coins in total
5/100 times x = 7
0.05 times x = 7
x = 7/0.005
x = 700/5
divide that you get 140
Answer:
68.5
Step-by-step explanation:
Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:
∠ACE = 180° -43° = 137°
Inscribed angle ABE has half the measure of central angle ACE, so we have ...
x° = 137°/2
x = 68.5
Answer:
3 + x
Step-by-step explanation:
Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).
Answer:
B
Step-by-step explanation:
the y- intercept is the point on the y- axis where the line crosses it
the line crosses the y - axis at (0, - 4 ) ← y- intercept
1. Let the given line be the graph of function f.
2. Let g be the inverse function f.
3. If f(a)=b then g(b)=a. So if point (a, b) is on the original line, point (b, a) will be on its inverse.
4. Take a look at the choices we have.
In A, the first point is (-2, -11), which means that in the line we should have (-11, -2). Clearly we don't.
In C, point (-11, 2) tells us that we should have point (2, -11) in the line, but clearly 2 is matched to a value close to -1
In D, (2, -11) indicates that (-11, 2) is in the lone, but is not even close.
ANSWER: B
check: All (-2, 11), (-1, 8), (0, 5), (2, -1) are in the given line
