15-20y
you simply distribute the factors.
5 x 3 = 15
5 x -4y = -20y
Final answer: 15 - 20y
OR
15 + (-20y)
19(.32) gives you 6.08 so yeahh
6.08 is 32% of 19
y = -7x - 13
y = -8x - 14 Subtracting:-
0 = x + 1
x = -1
From fisrst equation y = -7(-1) - 13 = -6
answer is x = -1 and y = -6
A chemical bond<span> is a lasting attraction between </span>atoms<span> that enables the formation of </span>chemical compounds<span>. The bond may result from the </span>electrostatic force<span> of attraction between atoms with opposite charges, or through the sharing of electrons as in the </span>covalent bonds<span>. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or </span>ionic bonds<span> and "weak bonds" such as </span>Dipole-dipole interaction<span>, the </span>London dispersion force<span> and </span>hydrogen bonding<span>.</span>
Answer:
x = 3
Step-by-step explanation:
Because the endpoints of the segment with length 12.5 are the midpoints of the sides of the large trapezoid, the length of that segments, 12.5, is the average of the lengths of the top and bottom lengths of the large trapezoid.
(3x + 1 + 15)/2 = 12.5
Multiply both sides by 2.
3x + 16 = 25
3x = 9
x = 3
